`((1 + costheta + sintheta)/(1 - costheta + sintheta))^n`

If Delta = |[1, 3costheta, 1], [sintheta, 1, 3costheta], [1, sintheta, 1]|, the maximum value of Delta is

Evaluate : 1/costheta + sintheta/costheta = ?

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

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

If x=(2sintheta)/(1+costheta+sintheta),t h e n(1-costheta+sintheta)/(1+sintheta) is equal to 1+x (b) 1-x (c) x (d) 1/x

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

Simplify : 1/( Costheta Sintheta ) + ( Costheta Sintheta )/( CosthetaSintheta )

If A = ((costheta,-sintheta),(sintheta,costheta)) then

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

If (costheta-sintheta)/(costheta+sintheta)=(1-sqrt(3))/(1+sqrt(3)) , then find the value of theta .
