If `4sintheta=3costheta` then prove that `(12sintheta-7costheta)/(8sintheta+3costheta)=2/9`

If sintheta + 2 costheta=1 ,then prove that 2sintheta-costheta=2 .

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

Evaluate : ( sintheta + costheta ) ( sintheta - costheta )

If (1+ sintheta-costheta)/(1+ sintheta + costheta)+(1+sintheta+costheta)/(1+sintheta-costheta)= 4 , then which of the following values will be suitable for theta ?

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

If sintheta+costheta=sqrt(2)sintheta , then sintheta-costheta=?

If : tantheta=(1)/(7), "then" : (2sintheta+3costheta)/(3sintheta+4costheta)=

If sintheta+costheta=x then sintheta-costheta=?

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