Hello,
On this video I show some basic formulas to in Mathcad.
On minute 1:04 I wanted to say SHIFT button plus ; (the button on the right of L letter in the keyboard). Sorry for this.
To download Mathcad go to this link :
https://www.mathcad.com/en
You can download the full version for 30 days. Also after these 30 days you will have access to the most important commands of Mathcad.
I really hope it helps you guys.
