To find the gradient of a function, that has constant gradient you pick any two points. You label both the x and y co-ordinates of these two points.Then you subtract the y co-ordinates of these two points...

x=-4, x=3

Answer: Integral= x³/3+ x/2 - cos(x) -1/4 sin(2x) + C Using the general rule that integrating xⁿ results in x⁽ⁿ⁺¹⁾/(n+1), x² integrates to x³/3.sin(x...

The easiest way to understand ionisation energy is to look at the equation for ionisation.For example, the ionisation of magnesium is shown by the following:Mg---> Mg⁺ + e^- The io...
