Difference between power series and fourier power series?
A power series is a series of the form ( \sum_{n=0}^{\infty} a_n (x - c)^n ), representing a function as a sum of powers of ( (x - c) ) around a point ( c ). In contrast, a Fourier power series represents a periodic function as a sum of sine and cosine functions, typically in the form ( \sum_{n=-\infty}^{\infty} c_n e^{i n \omega_0 t} ), where ( c_n ) are Fourier coefficients and ( \omega_0 ) is the fundamental frequency. While power series are generally used for functions defined on intervals, Fourier series specifically handle periodic functions over a defined period.
What are the applicaton of fourier series?
It can be used in function approximation, especially in physics and numerical analysis and system & signals. Actually, the essence is that the basis of series is orthorgonal.
Is the bar exam harder than the series 7?
I've never taken the Bar exam but I have taken the Series 7 Exam and passed my first try with a 94. The Series 7 is very comprehensive and contains information you are not likely to run into as a practicing financial advisor. You best prepare for 8 weeks or more if you have any hope to pass.
