Question

prove that cot square a + cos square a = cot square a

Answer 1

Answer:

I didn't under stand the question

Answer 2

Answer:

Hi guys

here is your answer

cot²a + cos²a = cot²a

LHS= cot²a +cos²a

cos²a/sin²a + cos²a [cot²a= cos²a/sin²a]

cos²a+ sin²a•cos²a

sin²a

1-sin²a + sin²a(1-sin²a)

sin²a. [sin²a+ cos²a=1]

1-sin²a + sin²a-sin²a

sin²a

1-sin²a

sin²a

cos²a

sin²a

cot²a

since LHS= RHS

Hence proved

Hope it will help u
