I don't know what equation to use or anything for this problem. Please help :) It is much appreciated!

**Reiny**, Tuesday, December 7, 2010 at 9:10pmthe equation must be

x^2 + y^2 = 1

(since .6^2 + .8^2 = 1)

2x dx/dt + 2y dy/dt = 0

divide by 2 and substitute

.6(3) + .8 dy/dt = 0

dy/dt = -1.8/.8 = - 9/4 or - 2.25
