Find an equation of the tangent line to the curve with parametric equations x=tsint, y=tcost at the point (0,-π).(adsbygoogle = window.adsbygoogle || []).push({});

went dy/dt / dx/dt --> cost - tsint/sint + tcost

t not given so figured it could be:

x=t(sin(1)) --> t= x/sin(1)

or

y=t(cos(1)) --> t= y/cos(1)

wondering if this is the right way to do it...looks really messy...help would be nice. Thanks.
