Question

1 + 10 square theta into 1 + cot square theta is equals to 1 / sin squared theta minus sin power4
theta

Answer 1

Step-by-step explanation:

1+tan^2A * 1+cot^2A= 1/sin^2A-sin^4A

sec^2A + cosec^2A =1/sin^2A-sin^4A

1/cos^2A+ 1/sin^2A = 1/sin^2A-sin^4A

1/(1-sin^2A)+ 1/sin^2A

Taking L.C.M

1/(1-sin^2A)(sin^2A)

Multiplying (1-sin^2A) and ( sin^2A)

1/sin^2A- sin^4A
