The question reads:
Consider the torus $T^2 = S^1 \times S^1$, parametrized in $\mathbb{R}^3$ by$$\Gamma(\theta, \varphi) = (\cos(\theta)(R+r\cos(\varphi)), \sin(\theta)(R+r\cos(\varphi)), r\sin(\varphi))$$ where $0
Now I believe I understand the first part, just find the derivative of the map and then parametrize it into $x,y,z$, but I am totally confused about the second part. Am I supposed to compute the map on the dual space of the tangent vectors at $p$? If anyone could help it would be greatly appreciated. Thank you.
