I read my exam's syllabus and come across these topic :
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 consider i as 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
