Hello,

I'm starting my adventure with Mathcad.

I have two the same files written in Mathcad 14 and Mathcad Prime 3.0.But it only works well in Mathcad 14 and I don't understand why.

In Prime 3.0 when i trying to plot the graph i have: "Plotting failed. Replace complex values and NaNs by real numbers."

I noticed that there are many people with similar problems. I have read all topics related to it and I still don't know what is wrong with my file.

Can you help me?

Mathcad Usage

Never type square brackets unless you really intend to create a matrix/vector. Otherwise type parenthesis only! Sometimes in real Mathcad and even in Prime they may be displayed as square brackets, but even you should never type square brackets yourself. In real Mathcad its not possible to enter that trap as typing "[" always will create a vector/matrix index, but in Prime after a multiplication dot it creates a matrix/vector.
