Hi everybody,
After I do implicit differentiation on my 50G, and solve for d1y(x), I have my result, which is d1y(x) = expression in terms of
x and y(x). So far so good. Now I want to plug constants in for x and y(x) and evaluate my derivative at a point. This is where I'm having trouble. I can't store a constant in the variable y(x), because that is apparently not a valid variable name. I tried using the define command to create a user function setting y(x) equal to a constant
..IE y(y(x))=3 , but that did not seem to work.
Is there any way to tell the calc that y(x) is equal to 3 when evaluating the results of my implicit differentiation?
Thanks, and best regards, Hal
Need help evaluating results of implicit differentiation.
