hi

how I can collect this number use my hand and calculator "fx-991ES"?
complex number

e^0.00931 e^j0.3730 in radiant

 

There might be a missing symbol in the expression. The first number is a plain or real number.

\(e^{0.00931} = 1.009\)

For the second expression you can use the Euler Identity

\(e^{jx}=cos(x)+j sin(x)\)

x is in radians

Can you do it without a calculator? Or are you relying on the calculator being a brain substitute?

You calculator supports polar entry of complex numbers. Converting your expression above to polar is trivial

Magnitude = e^0.00931
Angle = 0.3730 radians

Look at your owner's manual for how to enter the values:

Look on page 25.

 

I hadn't thought of an implied multiplication!

\(e^{0.00931} \cdot e^{j0.3730} = e^{0.00931+j 0.3730}\)

Duh!
