Question

the value of cot^2 alpha(sec alpha -1/1+ sin alpha)+ sec^2 alpha(sin alpha -1/1+ sec alpha ) is​

Answer 1

hey mate your answer

We need to prove (sinα+cosecα)

2

+(cosα+secα)

2

=k

2

+tan

2

α+cot

2

α

Taking LHS =sin

2

α+cosec

2

α+2+cos

2

α+sec

2

α+2

=5+1+tan

2

α+1+cot

2

α

=7+cot

2

α+tan

2

α

Therefore, k

2

=7

I hope it's helped you please make me a brainlist

Answer 2

Step-by-step explanation:

... alpha+cot^2 alpha+7(prove this) . Related Answer. Prove that: tan3α1+tan2α+ cot3α1+cot2α=secαcosecα-2sinαcosα.
