Question

IfTan theta+cot theta=2 then tan square theta+cot square theta=?

Answer 1

Answer:

Step-by-step explanation:

Given: tan theta+ cot theta=2

Squaring both sides we get,

tan2 theta +cot2 theta +2 = 4

Therefore, tan2 theta + cot2 theta =2 ans

Answer 2

Answer:

Step-by-step explanation:

Tan theta +cot theta = 2

Squaring on both sides

(Tan theta + cot theta )^2= 2^2

..

.

Tan ^2 theta + cot ^2 theta + 2 tan ×1/tan theta =4

Tan^2 theta +cot ^2 theta =4-2

Tan^2 thera + cot^2 theta =2
