Hi, 

I'm defining Theta to be between 0 to 90 degrees, and when I reference it in the subsequent lines, I get an error indicating I did something wrong. Please see attached.

Hi,

evaluate the range and then correct another errors.

Hi,
Thank you, I added the qual sign but then the sin^-1 is giving me the same error message "must be a scalar or matrix", but the same code in mahlab works, so its some syntax rule in Mathcad I'm missing here.

Hi

sin^-1 function does not exist. Use arcsin() or asin(). I cannot remember the right name of trigonometric function.

I fixed two errors, I think it has to do with defining one variable with a range in terms of another but I don't know how to fix theta_t error.
