Firstly, we need to differentiate the equation to find an equation for the gradient of the line.dy/dx = 6x-12We know the original graph was quadratic, and therefore only has one stationary point. This is ...

To get the smallest value of w-x we will need the smallest value of w and the largest value of x.Our smallest possible value of w=41.Our largest possible value of x=29.So the smallest value of w-x = 41-29...

(Suppose the coordinates of the point on the circle is (2, 3))To calculate the tangents equation we will first work out it's gradient. The tangent to a circle at a point is perpendicular to the radius of ...

Note that 1/4 as a decimal is 0.25, half of this is 1/8 which is 0.125.Multplying this by 5: we get 0.625

3l²mn + nl²m - 5mn²l + l²nm + 2n²ml - mn²
The first step is to ask yourself if there is anything that could help you simplify the equ...
