Using series like the Maclaurin series to approximate functions is important because it simplifies complex calculations, making it easier to analyze and predict the behavior of functions near a certain point (usually around zero). This is especially useful in calculus and numerical methods, where exact solutions might be difficult or impossible to obtain. Additionally, these approximations can help in understanding properties such as continuity, differentiability, and integrability of functions. Overall, they serve as powerful tools in both theoretical and applied mathematics.
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.
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.
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.

Simply because the Maclaurin series is defined to be a Taylor series where a = 0.
Best example is that an "odd" (or "even") function's Maclaurin series only has terms with odd (or even) powers. cos(x) and sin(x) are examples of odd and even functions with easy to calculate Maclaurin series.
Yes. If the Maclaurin expansion of a function locally converges to the function, then you know the function is smooth. In addition, if the residual of the Maclaurin expansion converges to 0, the function is analytic.
A maclaurin series is an expansion of a function, into a summation of different powers of the variable, for example x is the variable in ex. The maclaurin series would give the exact answer to the function if the series was infinite but it is just an approximation. Examples can be found on the site linked below.

The numerical value of pi is often found using a Taylor or Maclaurin series (Taylor series centered at 0).
