Inverse of Tan Theta

[lsingh-2]

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?

Regards,

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.

Sorry

It happens ever so often in this forum that pics are not correctly inserted or that the app would refuse the insertion of pics 😞

Usually creating a new post cures the problem.

Gentlemen,

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