Problem with fairly simple equation

Please you should attach the file.

The problem is the range variable for x which you defined.

Use the range for plotting, if necessary, but not for calculations!

Sorry don't know how to attach the file ... This is the equation I'm trying to write. I know you know how to do it, trying to get the

range of variables for all the values of x.

Thanks for your help so far.

Looks like there's some bigger problem when calculating e to the power of some variable rather than number. Any ideas?

Units for theta are meters.  You can't raise e to a power with units.

can you do this?

Fred Kohlhepp,

Thank you so much! The problem was with the units. I've been really struggling with this so it's a relief.
