There are two ways we can find the derivative of x^x. It's important to notice that this function is neither a power function of the form x^k nor an exponential function of the form b^x, so we can't use the ...

Always follow the same three steps : equating – substracting – substituting but you can have different cases : Case 1 : we only need to multiply one equation Example: 2x+5y=9 6x-4y=8 Note : Always check firs...

This problem is a graphical representation of finding the solutions to a pair of simultaneous equations. In this example we will use the curves y=2x 2 , and y=x 2 +1. This is a very straightforward example, ...

First things first it will definately be useful to make a quick sketch of the x-y axes, the two points, and roughtly what the perpendicular bisector will look like. This kind of question can be made much mor...
