If the point as `(4,7)` and `(costheta,sintheta)` , where `0

The locus of the point (a(costheta+sintheta),b(costheta-sintheta)) , where theta is the parameter, is

The distance between the points (costheta,sintheta) and (sintheta,-costheta) is

Find the slope of a line joining the points (sintheta, -costheta) and (-sintheta, costheta)

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

If the centroid of traingle formed by point (0,0) (costheta,sintheta) " and "(sintheta,-costheta) lies on the line y=2x, then the value of tan theta is

If cos(2theta)=0" then "|{:(0,costheta,sintheta),(costheta,sintheta,0),(sintheta,0,costheta):}|^2="............"

Find sintheta such that 3costheta+4sintheta=4 .

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