" 30.If "tan theta=(20)/(21)" then "(1-sin theta+cos theta)/(1+sin theta+cos theta)=

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

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

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 tan theta = 1/b , then ( a sin theta - b cos theta )/( a sin theta + b cos theta) is

(Sin theta -Cos theta +1)/(Sin theta+Cos theta -1) = ?

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

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

If 4tan theta=3, evaluate (4sin theta-cos theta+1)/(sin theta+cos theta-1)

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

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