Before starting any calculations it makes sense for the new practitioner to use the handy "soh-cah-toa" rule which means that you use: - sine with the opposite and hypotenuse sides to the angle. -c...

If you are given an equation with brackets, one way to solve it is to multiply out the brackets. Follow the example below: Solve the equation: 2(a + 5) = 16 1. Multiply out the brackets and remember that eve...

There's a nice trick here you can do, treat the equation as 1*ln(x) then intergrate by parts. Differentiating ln(x) gives 1/x, while intergrating 1 gives x So your left with a much easier intergration x ln(x...

First off, an explicit definition needs to be understood. An explicit definition is the standard form in which many equations are found: y = f(x) (1) for example: y=x 2 +2 Here, all values of y can be explic...

Pythagoras was a Greek philosopher who discovered that in a right angled triangle (triangle with one angle 90 degrees) the hypotenuse squared , c 2 , was equal to the sum of the other sides squared, a and b....
