3 dni temu · Find the value of $A$ where $$A=\sum_{n=1}^{\infty}\left(n\sin\left(\frac{\pi n}{2}\right)\left(e^x-1-\frac{x}{1!}-\frac{x^2}{2!}-\cdots-\frac{x^n}{n!}\right)\right)$$ By using the expansion of $e^x$ , I have simplified the expression into $$A=\sum_{n=1}^{\infty}\left(n\sin\left(\frac{\pi n}{2}\right)\left(\sum_{i=n+1}^{\infty}\frac{x^i}{i ...
3 dni temu · This modulo calculator is a handy tool if you need to find the result of modulo operations. All you have to do is input the initial number x and integer y to find the modulo number r, according to x mod y = r. Read on to discover what modulo operations and modulo congruence are, how to calculate modulo and how to use this calculator correctly.
5 dni temu · With this centroid calculator, we're giving you a hand at finding the centroid of many 2D shapes, as well as of a set of points. In just a few clicks and several numbers inputted, you can find the centroid of a rectangle, triangle, trapezoid, kite, or any other shape imaginable — the only restrictions are that the polygon should be closed ...
5 dni temu · If the function in the limit involves a square root or a trigonometric function, it may be possible to simplify the expression by multiplying by the conjugate. This method uses the algebraic identity. ( x - y ) ( x + y ) = x^2-y^2. (x −y)(x +y) = x2 −y2.

3 dni temu · An illustration of Newton's method. In numerical analysis, Newton's method, also known as the Newton–Raphson method, named after Isaac Newton and Joseph Raphson, is a root-finding algorithm which produces successively better approximations to the roots (or zeroes) of a real-valued function.The most basic version starts with a real-valued function f, its derivative f ′, and an initial guess ...
