Evaluate `sintheta/costheta`

Evaluate costheta.costheta+sintheta.sintheta

Evaluate costheta/sintheta

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

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

If tantheta-cottheta=0 , find the value of sintheta+costheta .

If tantheta = 3 , where 0^@ltthetalt90^@ , then find the value of (sintheta+costheta)/(sectheta+cosectheta)

If cottheta=4/3 , then find the value of sintheta, costheta and "cosec "theta in first quadrant.

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

Evaluate costheta/(1+sintheta)
