Hi

How do I do calculation and show working out with Imaginary and real Components in Mathcad Prime 3.1

For the value 16 / 20 °, calculate the real component

For the value 77 ⁄ 55 °, calculate the imaginary component. 


or


Find the real component of the addition of 15 ⁄ 60° and 38 ⁄ -66°

Thanks

Are you searching for something like this (should work in Prime, too):

In real Mathcad 15 (and below) you may even create a custom function and using infix operator you may make it look like

In Prime you have versor notation built-in

I'am too lazy to wait for Prime to fire up to take a screenshot, though.

Different input -> different output.

Compare the numbers in your first post which I had used with the number you are using now!

78 is not 77

16 is not 15

39 is not 38

Furthermore in the last line you have wrong parantheses. You take the real part only of the first summand and add it to the second complex number. Put the whole sum in parentheses!
