If `tantheta=3/4` , find the value of `(1-costheta)/(1+costheta)`

If tantheta=(3)/(4) ,then find the value of costheta .

If tantheta=(3)/(4) ,then find the value of costheta .

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

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

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

If cottheta=3/4 , then the value of sqrt((1+costheta)/(1-costheta)) is:

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

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

Answer the following by a number or a word or a sentence : If 4tantheta=3, then find the value of (4sintheta-costheta)/(4sintheta+costheta)

If sintheta=(7)/(25) ,then find the value of sqrt((1-costheta)/(1+costheta)) .
