Homework Help: Calc

Posted by Icy on Tuesday, May 8, 2007 at 9:39pm.

1. Determine an expression for dy/dt if x^2+2y^2=8 and dx/dt=3.

2. A point is moving along the right branch of a hyperbola defined by 4x^2-y^2=64. What is dy/dt when the point is at (5, -6) and dx/dt=3?

I will start you on the first, using implicit differention.

x^2+2y^2=8
2x dx/dt + 4ydy/dt=0
solve for dy/dt
