In the figure,

If P is the point (-`costheta,sintheta`), then find the length of OP, where O is the origin.

Evaluate costheta/sintheta

If sintheta=B/A then find the value of costheta

Evaluate costheta/(1+sintheta)

If Sintheta=costheta , find the value of theta

If y=x+c touches the ellipse 3x^(2)+4y^(2)=12 at the point P, then the value of the length OP (where O is the origin) is equal to

If P be the point (2,6,3) then the equation of the plane through P at right angles to OP, where 'O! is the origin is

If sintheta-costheta=1 ,then find sintheta.costheta

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

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

Evaluate [(1+costheta)/sintheta]^2
