`(sintheta+costheta)^2=1+2sintheta.costheta`

If 3cottheta=2 , find the value of (4sintheta-3costheta)/(2sintheta+6costheta)

(i) If tantheta=(a)/(b) ,then find the value of (2sintheta-3costheta)/(2sintheta+3costheta)

Prove: ((1+sintheta-costheta)/(1+sintheta+costheta))^2=(1-costheta)/(1+costheta)

Prove that: (1+sintheta-costheta)/(1+sintheta+costheta)=tan(theta/2)

Prove that: (1+sintheta-costheta)/(1+sintheta+costheta)=tantheta/2

(sintheta)/(1-cottheta)+(costheta)/(1-tantheta) is equal to (a) 0 (b) 1 (c) sintheta+costheta (d) sintheta-costheta

If 4 tantheta=3, then ((4sintheta-costheta)/(4 sintheta+costheta)) is equal to

If tantheta=(20)/(21) , show that (1-sintheta+costheta)/(1+sintheta+costheta)=3/7

If tantheta=(4)/(3) , then find the value of (3sintheta-2costheta)/(3sintheta+5costheta)

Prove that : (sintheta-costheta)/(sintheta+costheta)+(sintheta+costheta)/(sintheta-costheta)=(2)/(2sin^(2)theta-1)
