1. Find an equation for the tangent plane to the surface S(s, t) = (sin s cost, sin s sin t, cos s) at the point (s, t) = (π/4, π/2). Sketch the surface and its tangent plane

Recall the definition of a polynomial expression. find two polynomial expressions whose quotient, when simplified,is. use that division problem to determine whether polynomials are closed under division. then describe how theother three operations-addition, subtraction, and multiplication-are different from division of polynomials.
