Hi all,
I want to get some knowledge about MathCAD Prime and for better understanding I made some simple calculations.
I have done a simple example to get familiar with MathCAD solving functions.
I want to calculate the charging time of a capacitor for two different voltage thresholds.
have attached a pdf file of my MathCAD sheet.
What I have done in MathCAD delivers the right results but the intermediate steps are wrong.
Can someone explain me what I have done wrong?
Thank you for your help!
Hi.
Mathcad is like matlab: for numerical calculus. So, they dislike undefined variables. To avoid 'the red' you can use undefined variables as function parameters, like in the attached.
Best regards.

Can we use the variable in Matrix and solve them like AX=B, if all matrix is having the variables only no constants, can we solve those kind of matrix in Mathcad prime.
You may consider opening a new thread and attach a worksheet which shows a specific exemple of what you are looking for.
Which intermediate steps are wrong?
You have used variable names without having assigned numeric values to them first; the red outlines are the numeric processor complaining about that. There is no assigned value for , and the numeric processor is complaining. But that line is defining the variable "Calculation" to be the result of a symbolic solution. If you had typed:
instead of the third line, you would have created a function to calculate the time. And then solved for your times.
My solution:
