Question #01baa

Answer 1

I think the question should be to prove`tan x + cot x = 1/ (sinx * cos x)` instead of `tan x + cos x = 1/ (sinx * cos x)`

Explanation:

I think the question should be to prove`tan x + cot x = 1/ (sinx * cos x)`

`tan x + cot x` = `sin x/ cos x + cos x /sin x` =>

=`(sin x * sin x )/ (sin x cos x) + (cos x * cos x)/ (sin x * cos x)`

= `(sin^2 x + cos^ 2 x)`/ `(sinx cos x)`

= `1/( sin x cos x)`
