If `Cot( theta ) = 7/8` , then find `( 1 + Sintheta )/ ( 1 + Costheta )`

Show that : Costheta /( 1 - Sintheta ) + Costheta /( 1 + Sintheta ) = 2/Costheta

If cot theta= (7)/(8) then the value of ((1+ sintheta)(1-sintheta))/((1+costheta)(1-costheta)) = …………….

Evaluate : ( Cos^3theta + Sin^3theta ) / ( Costheta + Sintheta ) + ( Cos^3theta - Sin^3theta ) / ( Costheta - Sintheta )

Evaluate : ( 1 + sintheta + costheta )^2 =

Evaluate : (( 1 + sintheta ) ( 1 - sintheta )) / ( ( costheta ) ( - costheta ) )

If sin theta - cos theta =1/29 find the value of sintheta + costheta .

If   Costheta /( 1 - Sintheta ) + Costheta /( 1 + Sintheta ) = 4 ; then find the value of theta

If tan theta = 1 , find tha value of (sintheta + costheta)/(sectheta + cosectheta) .

If sintheta + cos theta =1 , then the value of sintheta - costheta is:

If sintheta-costheta=1 ,then find sintheta.costheta
