Could someone please give me a clue how to solve these parametric equations or a starting position.(adsbygoogle = window.adsbygoogle || []).push({});

torus specified by these equations

x=(R+rcosΦ)cosθ

y=(R+rcosΦ)sinθ

z=rsinΦ

calculate the normal to the torus N(θ,Φ) and entire surface area

p.s anyone recommend a book or a webresource that discusses this in detail as im very confused.
