Solve variable inside of trig equation?

[BB_14100646]

I'm using MathCAD 9.0.0.0. How can I use MathCAD to solve for theta? Below is the screen capture of what I have written so far. Attached is my MathCAD file.

Thanks,

To input an equation you hat to use the Boolean/comparison equal.

To get the desired solution I would suggest that you use one of Primes numeric methods.

You can use the "root" function by providing the interval from 0 to pi

Or you can use the "root" function by providing an appropriate guess value

Another option is using a solve block with "find". Its ugly looking and takes up much space, but here you have the option to add additional constraints

You may also use the symbolic engine with "solve", but as you are just looking for a numeric value I would not suggest doing so.
