Solve `sinthetacostheta-sintheta-costheta+1=0`

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

Prove (sin^3theta+cos^3theta)/(sintheta+costheta)=1-sinthetacostheta

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

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

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

If xsintheta+ycostheta=sintheta.costheta and xsintheta-ycostheta=0 find x^(2)+y^(2)

If sintheta+costheta=a and (sintheta+costheta)/(sinthetacostheta)=b , then (a) b=(2a)/(a^2-1) (b) a=(2b)/(b^2-1) (c) ab=b^2-1 (d) a+b=1

Solve: cos^(2)theta-sinthetacostheta-1/2=0

If (cos^(2)theta)/(1-tantheta)+(sin^(3)theta)/(sintheta-costheta)=K+sinthetacostheta , then K = ?

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