I think the question should be to prove $tan x + cot x = \frac{1}{sin x \cdot cos x}$ $tan x + cot x = 1/ (sinx * cos x)$ instead of $tan x + cos x = \frac{1}{sin x \cdot cos x}$ $tan x + cos x = 1/ (sinx * cos x)$

Explanation:

I think the question should be to prove $tan x + cot x = \frac{1}{sin x \cdot cos x}$ $tan x + cot x = 1/ (sinx * cos x)$

$tan x + cot x$ $tan x + cot x$ = $\frac{sin x}{cos x} + \frac{cos x}{sin x}$ $sin x/ cos x + cos x /sin x$ =>

= $\frac{sin x \cdot sin x}{sin x cos x} + \frac{cos x \cdot cos x}{sin x \cdot cos x}$ $(sin x * sin x )/ (sin x cos x) + (cos x * cos x)/ (sin x * cos x)$

= $({sin}^{2} x + {cos}^{2} x)$ $(sin^2 x + cos^ 2 x)$ / $(sin x cos x)$ $(sinx cos x)$

= $\frac{1}{sin x cos x}$ $1/( sin x cos x)$
