Prove the following trigonometric identities. please give a detailed answer because I don't understand this at all.
a. sin(x)tan(x)=cos(x)/cot^2 (x)
b. (1+tanx)^2=sec^2 (x)+2tan(x)
c. 1/sin(x) + 1/cos(x) = (cosx+sinx)(secx)(cscx)
d. tan^2 (x)(1+1/tan^2 x) = 1/(1-sin^2x)
e. sin^3 (x) +cos^3 (x)/(sinx+cosx) = 1-sinxcosx
f. (sinx-cosx+1)/(sinx+cosx-1)= (sinx+1)/cosx
You try the others. These are all pretty basic. The beauty of trig functions is the hundreds of ways they can be arranged and transformed into virtually unrecognizable forms!
Thank you for your help. It's just that I didn't take functions in grade 11 and now I'm taking Advanced Functions in grade 12 and I'm difficulty with. Thanks for your help though.
