Hi I've been asked to express a complex number in "Modulus-Argument
form". Is it the same thing/method as for Polar form?

Thanks

Sort of.
consider the complex number z where|z|=r and arg(z)=k. This number in modulus argument form is:
r(cosk +isink).
Think about right angle triangles, it makes senses that way.

That would be correct. Polar form is just another name. Although the exponential form is also sometimes called the polar form. In this case it refers to your cosines and sines.
