`(sintheta+costheta)/(sintheta-costheta)`

If sectheta=(13)/5 , show that (2sintheta-3costheta)/(4sintheta-9costheta)=3

if tantheta=(4)/(3) , then the value of (3sintheta+2costheta)/(3sintheta-2costheta) is

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

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

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

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

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

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

Prove that (sintheta-costheta+1)/(sintheta+costheta-1)=1/(sectheta-tantheta) , using the identity sec^2theta=1+tan^2theta

If 5tantheta =4," then " (5sintheta-3costheta)/(5sintheta+2costheta) is equal to
