11.5#1

Dear Professor Taylor,

I am struggling with this problem. For finding
dw/dt I am using the following for my partial derivative:
((y*(dx/dt)-x(dy/dt))/y^2)+((z*(dy/dt)-y*(dz/dt))/z^2). For each derivative
with respect to t I am taking the derivative of the expressions given for
each x,y,z.

You wrote y/x^2 when you meant y/z^2.
