When I'm trying to graph F(theta) an error tells me that the value must be a scalar and by error tracing, I found that in the first part of the if statement, the same error pops up. If anyone could help me out here that would be great.
Solved! Go to Solution.
I am glad to help you!
Better use not the Find but root function.
The Find is for 2, 3 and more equations.
And The root works in Mathcad Express - the free of charge version of Prime
