" 1f "tan theta=(20)/(21)" ,show that "(1-sin theta+cos)/(1+sin theta+c)

If tan theta=(20)/(21), show that (1-sin theta+cos theta)/(1+sin theta+cos theta)=(3)/(7)

If tan theta=20/21 , then the value of (sin theta-cos theta)/(sin theta+cos theta) is: यदि tan theta=20/21 , है, तो (sin theta-cos theta)/(sin theta+cos theta) का मान क्या है ?

If 21 tan theta=20 , then (1+sintheta+costheta):(1-sin theta+cos theta)=?

(xv) (cos^2 theta) / (1- tan theta) +( sin^3 theta)/ (sin theta - cos theta) = 1 + sin theta cos theta

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

Prove that: (sec theta + tan theta -1)/(tan theta - sec theta +1) = (cos theta)/(1- sin theta)

(tan A) / (1-cot A) + (cot A) / (1-tan A) = 1 + tan A + cot A = 1 + sec A cos ecA (1 + cos theta + sin theta) / (1 + cos theta-sin theta) = (1 + sin theta) / (cos theta)

(sin theta)/(1-cot theta)+(cos theta)/(1-tan theta)=(a)theta(b)1(c)cos theta-sin theta(d)cos theta+sin theta

Prove: (cos^2theta)/(1-tan theta) + (sin^3 theta)/(sin theta - cos theta ) = 1 + sin theta cos theta

Prove that (cos^(2) theta)/(1-tan theta)+(sin^(3) theta)/(sin theta - cos theta) =1 + sin theta cos theta .
