Question in manual:
Variables x and y are functions of t.
If (3x^2)y + 2x =2, and
dy= -4 when x=2 and y=-3,
then find dx
I can't isolate the equation for x, which is why I have to use the implicit differentiation, but I'm not sure how to set up the solution. Any ideas?
Thank-you for your replies. My question was not very clear. I understand the question is asking for dx/dt, and that taking the derivative of t comes first. Unfortunately I'm entirely confused as to how to the x=2 and y=-3 fit in, because the dx/dt format and derivatives in general are very new to me.
