Exponential form, polar form, Cartesian form for complex numbers question.

This is the question I have and I have no idea how to write the code!

Convert the complex number 8-7j into exponential and polar form. [2 marks]

I know already

syms a a=8-7j [theta, r]cart2pol(8, 7)

for the polar for but thats it

Find all five values of the following expression, giving your answers in Cartesian form: (-2+5j)^(1/5) [6 marks]

Any ideas?

Among others, see the Complex Numbers core MATLAB and the Symbolic Math Toolbox Complex Numbers documentation.

But how can I write in the script to display the complex number in exp form and polar form?

[Star Strider]

If I remember correctly:

Polar form:

p = @(z) [abs(z)  angle(z)];        % Polar (Phasor) Form , ‘z’ Complex

Exponential form:

e = exp(z);

Your textbooks and lectures haven’t discussed this?

Do a DuckDuckGo search on ‘Euler Identities’ for details.

My lecturer told us to teach our selves how to use it, and complete the assignment! Thanks for the help, it had me stumped!

My pleasure!
