How to add two terms to the same defined variable

[AS_10562569]

I am trying to type the following into Mathcad for a lab: 

 I can define F1:=(f1*cos(a1), but when I press enter to input the second function, Mathcad exists the math block. I have tried searching numerous forms, but have not found an answer on how to type this in. Ultimately it should produce the following: 

Any assistance would be greatly appreciated. I am working with Mathcad Express Prime 8.0.0.0

Type F Ctrl-- 1 : and then Press Ctrl-M to create a matrix/vector (you  may instead just type a [ ). Now type the first function call  and then Shift-Enter to create the placeholder for the second. Type it in and then leave the region by pressing Enter or left-click somewhere outside the region.

You may consider to study the help pages more thoroughly, maybe using the tutorials, too, for a first flight ...

Hi,

Elaborating on Werner's answer there are two ways to enter the F1 matrix (square brackets)

a) element by element using keystroke [ to set the element index to F1. Elements start numbering at 0 by default.

b) create the two element matrix and fill in the rows. Matrices have square brackets around them.

Cheers

Its rather f1:=170 N and alpha1:=111°  🙂
