I am trying to leave an expression in a phasor (Euler's Form) format. If my angle theta is a non-decimal number it remains in the form I desire: In[1]: Exp[I 3] Out[1]: Exp[I 3] However, if my angle is a decimal approximation, Mathematica converts to a rectangular format: In[2]: Exp[I .3] Out[2]: 0.955336 + 0.29552 I I would like to have the output remain in phasor notation. Can you help? The specific problem I was working with was: In[3]: Exp[I ArcTan[1/8]] When I tried to numerical approximate the ArcTan[ ], Mathematica shifted to the rectangular format. I have tried numerous techniques but to no avail. Capt Paul Simonich Dept of Mathematical Sciences U.S. Air Force Academy
