Question

Help me guys,with steps plz

Answer 1

Step-by-step explanation:

tan$ - cot$ = sin$/cos$ - cos$/sin$

= (sin^2$ - cos^2$)/sin$cos$

COS^2$ = 1 - SIN^2 $

therefore

= (2sin^2$ -1)/sin$cos$

Answer 2

Answer:

Step-by-step explanation:

tan x= sin x/cox

cot x = cos x/sin x

Therefor-:

tan x - cot x = (sin x/cos x) - (cos x/sin x)

                   = sin²x -cos²x/cos x*sin x

putting the value of cos²x = 1-sin²x

                  = 2sin²x - 1/sin x*cos x
