CHAPTER 4 FOURIER SERIES AND INTEGRALS

The simple reason for this can be found by looking at the function g (t)=f (t)-a0 [note: g (t) is the square wave with the constant offset removed so that the average of the function is zero]. It turns out that g (t) is an odd function, and

Here I can show you my steps: F(x, y) = ∞ ∑ m = 1sin(mπx) ∞ ∑ n = 1sin(nπy)Am, n = ∞ ∑ m = 1( ∞ ∑ n = 1Am, nsin(nπy))sin(mπx) = ∞ ∑ m = 1Bmsin(mπx) and so Bm = 2 L∫L0F(x, y)sin(mπx)dx

Note that the Fourier coefficients are complex numbers, even though the series in Equation [1], evaluated with the coefficients in Equation [4], result in a real function. If the following condition (equation [5]) is true, then the resultant

First, recognise that the fundamental period of the signal x (t) (sum of two sinusoidals with periods 2/3 s and 1/50 s) is 2s. And the fundamental frequency, f 0, is 0.5 hz.

Clear up math questions

Very easy to use, and always gives the right answer, it's absolutely perfect, doesn't need an Internet connection and explains what you must do in a clear and essential way, but after giving solution of two answers it asks for upgradation which means you have to pay money for further sums.

The pic feature is nice too but feels like I'm cheating. Didn't pay attention in math at all, but this helped me ace my quiz, and helped me understand everything better. Well so far it works good and I appreciate the solutions that it provides. I should give 5 stars, a very good app for finding out the answers of mathematical equations and also a very good app to learn about steps to solve mathematical equations.
