An ion can be an atom or a group of atoms that are charged. This means they can be positively charged or negatively charged.A positive ion is formed when the atom loses electrons. Because electrons have a...

First we need to find the complementary function - the solutions of y'' -3y' + 2y = 0. By setting y=Ae^(kx) (A is a constant) we get :A(k^2 - 3k + 2)y = 0. This means k^2 - 3k + 2 = 0 =(k-1)(k-2). If 2 th...

The working memory model (WMM) was put forward by Baddeley and Hitch. The model consists of 4 main features; central executive, phonological loop, visual-spatial sketchpa...

So it is easiest if we first draw out the triangle and label it.We use an equation called Pythagoras' Theorem. This equation is A^2 + B^2 = C^2So we know the length of side A (3) and side C (6), lets put ...

formula= fg-integral(f'g)So we have:xln(x)-x+C
