Question

Inverse of Tan Theta

Hi All,

In MathCAD Prime 2 I am trying to write inverse of tan to get the value of theta. Please see attached.

1. I am not getting the right answer (please see file 1). The value of theta should be 36.86.

2. I am not being able to write it (please see file 2).

Can someone please advise how to correct this?

See please the atan function.

As alread advised by Valery - use atan(). Thats what arctan() is in my math books and what atan^-1 is on your calculator.

The result will be in radians, to get it in degree simply put the desired unit after the result.

Gentlemen,

Thanks for your help, much appreciated. I thought writing tan inverse was straightforward and struggled on this for a few hours.
