just wondering if this can be done to facilitate proofs

Answer 1

Favorite Answer

yes

Answer 2

yep it is true! ...look at this

tanx^2=(sinx/cosx)^2 .... square root both sides u get tanx = sinx/cosx

still unsure?

Try any value for x lets say x=44

(tan44)^2 = (sin44/cos44)^2

both sides u get 0.932554809...

so there it is tan^2 = (sin/cos)^2

BEST ANSWER PLEASEE!!!
