When you use the n/d template, a fraction cannot contain a complex number.
You can use division to compute the answer:
Note about Radian Versus Degree Mode
Radian mode is recommended for complex number calculations. Internally, the calculator converts all
entered trigonometric values to radians, but it does not convert values for exponential, logarithmic, or
hyperbolic functions.
In degree mode, complex identities such as
e^(iq)=cos(q)+i sin(q) are not generally true because the
values for cos and sin are converted to radians, while those for e^() are not. For example,
e^(i45) = cos(45) + i sin(45) is treated internally as e^(i45) = cos(p/4) + i sin(p/4). Complex identities are
always true in radian mode.
Interpreting Complex Results
Complex numbers in results, including list elements, are displayed in either rectangular or polar form,
as specified by the mode setting or by a display conversion instruction.
In the example below, polar-complex
re^ (qi) and Radian modes are set.
Rectangular-Complex Mode
Rectangular-complex mode recognizes and displays a complex number in the form a+bi, where a is the
real component,
b is the imaginary component, and i is a constant equal to .
