Best ResponseYou've already chosen the best response.0oh come on help me out here :( i don't know how to use the confunction identities for cot.

Best ResponseYou've already chosen the best response.0tan=sin/cos cot=cos/sin sin(xpi/2)=cos(x) etc

Best ResponseYou've already chosen the best response.0I mean my advice to you is to rewrite cot as cos/sin

Best ResponseYou've already chosen the best response.0cos/sin=cot so cos=sin or cos = tan or cos = sec but thats only if cos(pi/2u) but thats not the case in my problem

Best ResponseYou've already chosen the best response.0my problem is (xpi/2) not (pi/2x)

Best ResponseYou've already chosen the best response.0do you know even odd functions? sin(x)=sin(x) and cos(x)=cos(x)

Best ResponseYou've already chosen the best response.0hence sin(xpi/2)=sin((pi/2x))=sin(pi/2x) and apologies for the typo earlier

Best ResponseYou've already chosen the best response.2\[\cot (x\frac{\pi}{2})=\frac{\cos (x\frac{\pi}{2})}{\sin (x\frac{\pi}{2})}=\frac{\cos x \cos \frac{\pi}{2}+\sin x \sin \frac{\pi}{2}}{\sin x \cos \frac{\pi}{2}\cos x \sin \frac{\pi}{2}}\]

Best ResponseYou've already chosen the best response.0really though you need to negate your stuff on the inside and apply even odd functions to tak eout the negative sign and rewrite cot(xpi/2) to cot(pi/2x) (expand cot to cos/sin to do this)

Best ResponseYou've already chosen the best response.2\[\frac{\cos x(0)+\sin x(1)}{\sin x(0)\cos x(1)}=\frac{\sin x}{\cos x}=\tan x\]

Best ResponseYou've already chosen the best response.2And now you have proven the given identity once and for all.

Best ResponseYou've already chosen the best response.0ooooh i see i thought you had to make both of them negative thus making it tan=tan i get it now ty!!!

Best ResponseYou've already chosen the best response.0that was an intense one.. It probably needed one of the sum or difference identity formulas. right after rewriting cotx = cosx/sinx

Best ResponseYou've already chosen the best response.0then evaluate it at pi/2 or 90 degrees ... terms cancel and viola tanx = tanx
