Solve `sintheta/(1-costheta)+sintheta/(1+costheta)=4`

The value of (sintheta)/(1+costheta)+(sintheta)/(1-costheta) is :

If : (1+sintheta)/(1+costheta)+(1-sintheta)/(1-costheta)=2u.(csctheta-costheta),"then" : u =

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

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

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

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

Prove that : (i) (1-cosA)/(sinA)=(sinA)/(1+cosA) (ii) (costheta)/(1-sintheta)=(1+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 ?

(sintheta+costheta)/(sintheta-costheta)+(sintheta-costheta)/(sintheta+costheta) =_____________.

Solve for x : x^2 - ( sintheta + costheta ) x + sintheta costheta = 0
