Expand function symbolicaly. Set X-axys and result value to angle in degrees.

[pbus]

I have some questions. I have uploaded the Mathcad 14 file and here is a image of it.

Show expanded function without replacing the variable per its values.

Result in degrees. it wont let me select any unit.

Only positive result. If I add: assume θ>0 the solve fails! Why?

x-axis (θ) in degrees, not rad. The range is set from 0°-90° but it is still displayed as rad!

If you type h:=5, you define the variable h to be equal to 5. If you then ask the symbolic solver to manipulate an expression with h, it first substitues the number 5 in place.

Unless

you type h := h

Then the symbolic solver will continue to use the variable name. (Strange, isn't it.?

To get a plot with units to display correctly (in version 14 and 15, and anything before), divide by the unit.
