Does anyone find this hard? I find it quite easy but it gets a little tricky with all the crap you have to memorize. Like SOH CAH TOA. This is what we use to memorize it. But Trigonometry gets harder when you get To higher levels of it. Like Sine Law can be quite tricky. Well I must say im pretty good at this. Did trigonomety ever piss you off?
 
I must admit...when it comes to Math, I'd consider Trig to be one of my weak areas. I understand the basics and such (like the definition of sine, cosine, etc.), and I know the basic identities (sin^2+cos^2=1, etc.)...but sometimes I forget the more complicated identities (double/half angle formulas)...and dealing with trig in higher-order mathematics can be a little dicey.

And I still don't quite have the unit circle memorized. -_-
 
I find it slightly difficult in A-Levels where you go into more detail about it. At GCSE it was pretty easy. Personally, I find Maths Mechanics the harder part of Maths A-Levels, mainly due to the fact that I don't know which pat of the question goes into which part of the equation....
 
I really like Algebra but Geometry bugs the shit out of me. Granted, I'm still pretty good at it, but it bugs me and gives me more trouble. Too much memorization also.
 
Trigonometry is easy. It's the easiest thing I ever have to do in any math class ever. >.> Whenever a class I'm taking gets to the trig section, my grades take a huge upswing by the end of all the chapters (like the one right now where I can get my grade up to an A if I ace the rest of the tests...). To me, it's the most useful and I can think of all sorts of ways I can use it.
 
trig was hard for me in high school. i was expecting to place into trig in college but some how i was able to place in calculus so that was good that i didn't have to take it again in college. but then calculus was even harder, but all that matter is that i passed it. but i didn't like trig much, and i think college trig would have been a lot harder than high school trig, glad i didn't have to takte it again

Agreed, trig in pure maths is unpleasent. SOHCAHTOA is what you learn when you're about 14, then after they introduce theta but you've still got numbers and it's all very easy to solve.
But when it's Cos(A+B) = cosAcosB - sinAsinB it's more difficult.
Fortunately all you need for an economics degree is stats, so the only thing close to difficult is calculating the standard error, but that's all formulaic.
 
I hate Trigonometry, but it is neither due to the course nor the memorization, it is because of the Professor. He simply comes, copies the damn book on the blackboard, and makes like hundreds of mistakes so we have to edit what we copy in our textbooks like three or five times during the whole class. He also goes too fast when explaining the examples, and half of the class has switched to another professor while other unfortunate idiots (like me) were stuck with him.

The professor even admits he sucks when teaching Pre-Calculus, albeit he is a great Calculus professor (does not makes much sense but meh...). Now I am on the verge of failing this course and having to repeat it (which is a severe ego killer). Oh but Hell knows I won't be taking the class with that professor, ever, again.
 
I actually really liked Trig, once I understood it, it came naturally, kind of like Physics. And for SOH CAH TOA, we were taught to think Some Other Hippie Caught Another Hippie Tripping On Acid, clever huh? When you start doing Calculus, then Trig just makes the process that much more painful. Doing Integration by parts with Trig is just a freaking nightmare.

Actually Roxas, Pre-Calc and Calculus are totally different. I took a class in high school called Elementary Functions which was a half a year for Trig and a half a year of Pre-Calc. I then went to Calculus the next year. Then when I was placing into a math class in college, I got 4/25 right on the Pre-Calc section but 12/25 on Calculus. I ended up getting placed in Calculus because I clearly knew it, even though I had no idea in Pre-Calc. Pre-Calc kind of gives you some of the more conceptual stuff while Calculus you actually apply that concept. I guess it's more if you're better at understanding or doing the work.
 
I love maths! but don't tell anyone because they'll think i'm a geek... D:

I just did a test on that at school so anything you don't understand ask me
 
I didn't find it hard at GCSE, just somewhat useless and pointless since I knew fine well I was taking maths at A-Level, I still don't see what the point of it is, unless someone would like to enlighten me? :wacky: It was boring as well, I think for the majority of the trig chapter of the book I ended up playing squares next to the person sat next to me >.>
 
Its for working out the angles or sides of a triangle. That's why it's called TRI-gonometry. BTW, I got the silly thing of TWEWY.
 
Yeah I know that bit but like, why's it needed? When's working out the side of a triangle going to be useless for anything?..unless you're making a bridge possibly, which I have no intention of doing, so I spent 3 years doing trig which at the end of the day has become entirely pointless. -__-
 
LoL I do believe you are talking about geometry. Geometry was an easy A. Trig is no easy matter, go to university and learn the real trig, and you will pull your freakin hair out. To be an engineer you have to learn it. While most people say Calculus 1 and 2 were impossible I pulled off an A and B. When I took Trig I miraculously got a C. The stuff is very complex.
 
Well....trigonometry is a little more complicated than just triangles. *ahem*

Trigonometry is essentially based on two functions, Sine and Cosine, which take any real number and assign it a value between -1 and 1. All of the other Trig functions (tangent, secant, etc.) can be written as a ratio of the basic two. What we've found, though, is that these functions can also describe the relationship between sides of a right triangle.

I say that to say this: viewing trig expressly through the lens of "triangles" limits your views of what it can really do. The fact that trig functions are periodic (repeat themselves over particular intervals) is far more useful, especially in the field of Physics. Trig functions can describe basically ANY harmonic motion (springs, oscillating bridges, guitar strings, diffraction of light, etc). Admittedly, beyond the field of Physics and such, Trig isn't terribly useful...but it's good to learn to solve problems and exercise your mind nonetheless. :awesome:
 
I took Trig this year, and I hated it, thanks to my teacher -___- It isn't that he doesn't understand the subject or know how to teach it, it's just the way he teaches it. His writing is extremely small and hard to read, and he speaks so soft that hardly anyone can hear him. Sadly, I had to get a close friend and peer of my to teach me everything, and she had to teach herself everything. I was going to take Calculus next year, but I decided not to since my current teacher is going to be teaching it as well.

You've pretty much summed it all up. I actually first learned trig with its relations to triangles, then expanded to oscillations. In the engineering field, pretty much any form of it, it will always be useful. Personally, I'd rather not deal with trig, but it's the only way to go about certain problems. If ever you take a course in Vibrations, you'll get to see dampened oscillation. Yeah, adding logrithmic functions to trig just gets annoying, but its not too scary.

Trig tends to be difficult for most people to wrap their head around, so it's natural that others find it tough. It's like physics, it may seem impossible to figure out at first, but one day a light bulb goes off in your head and things start to make sense. For all of those who have difficulty with it, just be patient and it'll become easier to swallow. For those getting into calculus, differentiating trig functions can get very nasty, as they don't break down like linear functions. It gets to be long and messy.
 
I really enjoyed it until the last part of my A Levels. I have to do integration of functions and they usually have trig functions in them, then you have to use trig identities, then simplify... it was pretty hellish.
I always remember SOHCAHTOA cuz it sounds like a martial artist using a judo chop! (when said quickly)
 
I suck badly in Trigs (and math in general except Algebra). I just took the GCSE Math test a few weeks ago and I have a 50% chance of failing it. The trigonometry problems were "easy" (for everyone else) but I couldn't do it.:wtf:
