y = x³ + 1.5x² -6x Hence, dy/dx = 3x² + 3x - 6 Solve to find x when dy/dx = 0 as gradient is zero at stationary points Substitute the vaules for x back into y to find y co...

There are 2 methods to solving this- the visual method and the kinesthetic method. Here I will use the visual one. We start by creating a vector triangle. We are going to use R = P + Q, where R is the res...

In this poem, Bishop's use of language creates a tongue-in-cheek appraisal of lost love, time and chances. The beginning of the second stanza mimicks the tone of a self help guide, turning to address the ...

(1.) Integrate the expression for acceleration to find an expression for velocity: Velocity v = t^2 - 3t + c        When t = 0, velocity = 2. Substituting in to find constant c, 2 = 0 + 0  + c therefore c...

Differentiation is essentially a method of finding the gradient of a function. To put that in better terms, imagine you have a graph of y=x, this is a straight line which means the gradient will always be...
