Help with implicit differentiation.

[rking-2]

I am trying to use MathCad Prime to solve an implicit differentiation but I have no idea how I could do it.

It seems to only solve a normal differentiation (functions).

Example (circle equation):

x^2+y^2=25

dy/dx=-x/y

How do I get MathCad Prime to work properly with implicit differentiation?

Thanks!

Use symbolics to solve for y, then take the derivative.

See attached for an example problem.

Please don't post the same question twice. It means answers can get split between two threads.

It's not clear to me exactly what you want to solve for. Please clarify.

I have seen that second post too late - please don't crosspost!
