This question involves rearranging equations. In this case we need to get t on the LHS (left hand side) of this equation in order to find an expression for t. An expressi...

First we can to start by making a sketch of the triangle since it may be easier to visualise the problem. Since the median of a triangle is a line that joins a vertex to the midpoint of the opposite side,...

Label both equations to make it easy to refer to them in your answerEqn 1: 4x+5y=-3Eqn 2: 6x-2y=5To solve these equations we need to be able to eliminate either the y terms or the x terms. In ord...

This may be initially confusing to get your head around but gradient is really just an expression of "rate of change" on a curve the rate of change is always changing at every point, this abou...

dy/dx = 6x² - 3x + 4
To retrieve the original function y from dy/dx you have to integrate the derivative with respect to x.
y = ∫(dy/dx)dxy = ∫(6x² - 3x + 4)dx
To inte...
