You have no idea how had it gets, you go from sine,cos,tan to Cosec,Sec,cot, and even further. You have to use identities to get from stuff like 4Cosec^2x+cosecx to something like 1/cos. and it would only be like 2 marks
Forced to do 1 year of uni level calculus and modelling for my science degree when i only did normal level maths in high school... Trig identities arent even worth marks or at most 1 if its like the first question...
Yeah like turning sinxcosx^2 to tanx or something. That's an easy example but you get the point. I asked my teacher when we would ever need to know this and she goes "well you need it for college." I'm sitting there thinking "well if that's the last time we need it then why the hell do we have to do this **** ?!"
It's stupid
School isn't about teaching you stuff you have to know, it's really about becoming well rounded and getting a work ethic. What you just said about math you could say for most classes in school.
Had a japanese physics teacher and a kid in the class who couldn't stay on track. Teacher thought he kept telling the kid to focus, but in reality he just shouted that the kid needed to **** us whenever they started rambling...
The Pythagorean theorem is the joke. The area of the squares is equal to the sides being squared. The area of the legs (a and b) are equal to the area of the hypotenuse.
But not in this particular example. Just about every math concept that is covered can be used by physics but unless it is being used it that specific regard I don't consider it science. It's a personal definition as all. For instance pythagorean theorem by itself is not science, but finding the magnitude of two force vectors intercepting at a right angle, which uses the pythagorean theorem is science, to me at least. But for now let's just agree to disagree.
