Question

Cos square theta + 1/1+cot square theta =1​

Answer 1

cos^2 A+1/1+cot^2 A = 1

Answer:

we know:

1+cot^2 A=cosec^2 A

Therefore,

cos^2 A+1/cosec^2 A = 1

i.e. cos^2 A + sin^2 A                      {1/cosec^2 A= sin^2 A}

i.e. =1                                                  {cos^2 A + sin^2 A =1}

LHS=RHS

Thus proved
