To calculate the perimeter (the length of the outside edge) of a square, you must add up the length of each side. Here, we have been given the area of the square. The area of a square is calculated by squ...

We first see that we are asked to solve the equation in terms of y. We can see that y = 2^x, and there is also a 2^x in the equation, meaning we can instantly change that to y. However, there is also a 4^...

1 find the domain of the function (where it exist) 2 find the solutions of the function, solve f(x)=0 3 if it has vertical asyntotes (poles) identify them (eg the denomitator=0) 4 find the intesections wi...

To be able to solve a quadratic, you must make it equal to zero. So the first thing you have to do is take away 5 from both sides. You could take away 6x^2-13x from each side, but it is much easier to kee...

The gradient is the rate of change at a specific point on the curve. Since the tangent is a straight line that touches the curve only once at a specific point, the gradient of the curve and the tangent wi...
