I know I am making a stupid mistake but I am not sure what it is...(adsbygoogle = window.adsbygoogle || []).push({});

Find an equation for the plane tangent to the torus X(s,t)=((5+2cost)coss, (5+2cost)sins, 2sint) at the point ((5-(3)^1/2)/(2)^1/2, (5-(3)^1/2/(2)^1/2, 1).

First I have to find what s and t are in order to sub them in for dT/ds and dT/dt. So first I solved for t using 2sint=1 and get t=pi/6. However, when I attempt to sub it into one of the other equations to solve for s I get 2 different answers for s when using each of the different equations. What am I doing wrong?
