If I have the equation of a curve, how do I find its stationary points?

A stationary point is where the gradient of a curve momentarily stops changing.Let's take the example that we want to find the stationary points of the curve y=2x^5 - 5x^2. Find the derivative of the equatio...

prove that any odd number squared is one more than a multiple of four.

any odd number can be written as (2n+1), where n is any integer (whole number). Squaring any odd number is therefore= (2n+1) 2 . expanding the brackets gives =4n 2 +2n+2n+1 2 = 4n 2 +4n+1. factorising the 4 ...

how do you know if two straight lines on a graph are parallel or perpendicular?

On a straight line graph, the lines are formed by an equation in the form y=mx + c . The m value in this equation represents the gradient, and the c value is the y-intersect.If two lines are parallel, this m...

For the function f(x) = 4x^3 -3x^2 - 6x, find a) All points where df/dx = 0 and b) State if these points are maximum or minimum points.

Part a) requires you to find df/dx for the given function. To do this, we differentiate the function once, which is done by multiplying the power of each 'part' with the part itself and subtracting 1 from th...
