I read my exam's syllabus and come across these topic :(adsbygoogle = window.adsbygoogle || []).push({});

1. De Moivre’s theorem for an integral exponent (without proof)

2. The idea of area under a curve as the limit of a sum of areas of rectangles.

My teacher never taught the class about this topic. I want to ask what these topics about.

De Moivre’s theorem for an integral exponent

Is this the meaning :

[tex]\int ~e^{i \theta}~d\theta~=~\int ~(\cos~\theta~+~i\sin\theta)~d\theta[/tex]

Then we considerias a constant and just do simple integral?

For the second one, I don't know the meaning...

Can anyone give me a clue what I shoud study about these two topics. Thanks
