Question

P.T. 1+tan²theta/1+cot²theta = (1-tan theta/1-cot theta)²​

Answer 1

Step-by-step explanation:

=tan a1- tan a +1tan a1-tan a

=tan2 atan a -1 -itan(tan a - 1)

=tan3 a - 1 tan(tan a - 1)

=1 +tan2a +tan atan a

1+tan a+ cot a

Answer 2

Answer:

P.T. 1+tan²theta/1+cot²theta = (1-tan theta/1-cot theta)²
