Simplify `sintheta-costheta=0`

Simplify costheta[costhetasinthetasinthetacostheta]+sintheta[sintheta-costhetacosthetasintheta]

Simplify (sintheta+sectheta)^(2)+(costheta+cosectheta)^(2) .

Simplify: cos theta[{:(costheta,sintheta),(-sintheta,costheta):}]+sintheta[{:(sin theta ,-costheta),(costheta, sintheta):}]

Simplify (1-costheta)/sintheta

Simplify (1-costheta)/sintheta

If sintheta+costheta=sqrt(2) , then find the value of sintheta-costheta .

If 5tantheta-4=0 , then value of (5sintheta-4costheta)/(5sintheta+4costheta) is

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

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