When solving an angle for a right-angled triangle you need to use the acronym SOH CAH TOA, using the functions sin(x), cos(x) and tan(x). The other letters O, H and A represent the side of the triangle, s...

First, for this graph dy/dx = 2x-8. At a turning point of any graph, dy/dx=0. Therefore 2x-8=0. x=4. Plug x value back into original graph formula : (4)^2 - 8(4) + 25 = 9. Therefore y=9. Coordinates : (4,...

This is an example of completing the square. Completing the square means taking a usual quadratic equation ax²+bx+c=0 and writing it as a(x+d)²+e=0, where we must find the numbers d ...

At first, it is important to identify that this is a linear equation, usually in the form of y = mx + b. These equations are used for straight line graphs. The most important rule to remember when solving...

The first piece of understanding needed to answer this question is that integration can be used to find the area under a graph between two points. However, before we can integrate we must find the bounds ...
