`2cos^2theta+2/((1+cot^2theta))=2`

cos^(2)theta+1/(1+cot^(2)theta)=1

Prove: cos^2 theta + 1/(1 + cot^2 theta) = 1

Find the value of (1 +cot^2 theta )(1-cos^2 theta ) (1 +cot^2 theta )(1-cos^2 theta ) का मान क्या है?

If (sin^(3)theta-cos^(3)theta)/(sin theta-cos theta)-(cos theta)/(sqrt(1+cot^(2)theta))-2 tan theta cot theta=-1 (AA theta in[0, 2pi], then

If (sin^(3)theta-cos^(3)theta)/(sin theta-cos theta)-(cos theta)/(sqrt(1+cot^(2)theta))-2 tan theta cot theta=-1 (AA theta in[0, 2pi], then

(1-cos^(2)theta)(1+cot^(2)theta)= ………. .

The value of (1 - cos^(2) theta) (1 + cot^(2) theta) is ……….. .

Simplify: cos^(2)theta+(1)/(1+cot^(2)theta):

Prove that : (tan^(2)theta)/(1+tan^(2)theta)+(cot^(2)theta)/(1+cot^(2)theta)=1
