Homework Statement Find the points on the graph of z=(x^2)(e^y) at which the tangent plane is parallel to 5x-2y-.5z=0 Homework Equations An equation of the tangent plane to z=f(x,y) at (a,b) is: z = f(a,b) + fx(a,b)(x-a) + fy(a,b)(y-b) The Attempt at a Solution Partial derivatives...

Actually this is no a homework question, its from a placement practice exam. So I didn't really know where to look for things. But, I think I have solved the 2nd. So Now just need help with 1st. The attempt at a solution 2. z=x^2-y^2 and z=x^2+xy-1 x^2-y^2 = x^2+xy-1 ...

No, I don't.

Hey, Can anyone please help me sove these problems: These are two different problems form different sections. 1. Show that one arch of the cycloid r(t) = <t-sint, 1-cost> has length 8. Find the value of t in [0,2pi] where the speed is at a maximum. 2. Find a parametization of the...
