A destructive plate boundary exists when a continental and oceanic plate boundary meet. The oceanic plate descends underneath the oceanic plate as it is denser.  The build-up of friction between the two p...

Supposing we have two equations x+2y=5 and 3x-y=10 and we want to find x and y we can use the following techinque. Multiply both the RHS and the LHS of the second equation by 2, giving us 6x-2y=20. Then a...

The derivative is a measure of the rate of change of f(x) as x varies. Alternatively it is the gradient of the tangent at a specific point of the graph. There are different rules for finding the derivativ...
