" Ex.18"(sin2 theta)/(1+cos theta)" equals "

(sin theta)/(1+cos theta) is equal to

(cos theta)/(1 + sin theta) equals

1-(sin^(2)theta)/(1+cos theta)+(1+cos theta)/(sin theta)-(sin theta)/(1-cos theta) equals

What is ( sin theta - cos theta + 1 )/( sin theta + cos theta -1) - ( sin theta + 1 )/( cos theta ) equal to ?

What is (sin theta+1)/(cos theta) equal to?

1-(frac(sin^2 theta)(1+cos theta))+(frac(1+cos theta)(sintheta))-(frac(sin theta)(1-cos theta)) equals…..

Prove that: (a) (sin 2 theta)/(1+cos 2 theta)=tan theta (b) (1+sin 2 theta+cos 2theta)/(1+sin2 theta-cos 2 theta)=cot theta

(cos theta)/(1 - sin theta) + (cos theta)/( 1 + sin theta) equals
