Find Definition Problem

[Raiko]

hello Folks,

the first MC15 sheet (find_1) has a solve-block which doesn't compute. The second (find_2), with a slightly different definition, however does. Can anybody explain why this is the case?

Tanks in advance

Mathcad is complaining that f(x) (and g(x)) ist not defined and thats true. How could the algorithm play around with x so that f(x)=x^2 or  f(x)=h(x), when it cannot evaluate f(x)?

You have to define your functions using the definition operator ":=", not the boolean "=".

And normally you would do this outside of the solve block.

Thank you Werner.

I knew that it had to be my fault 😉
