There are 2 handy ways of remembering how to do these questions, so I'll show you both and you can tell me which you like best. What's important to remember is to make sure you times everything in the fir...

Implicit differentiation can be used when you are asked to find dy/dx of a function that has not been written as y=f(x) e.g. y = x^2 - 1, and which cannot be rearranged as such. We can use the equation of...

The question is asking us to find the first derivative of the function (y) with respect to x terms.y = (3x -1)^10We start by taking the superscript 10 down to the front, and multiply this by the 3 (as per...

We know that the equation of a line takes up the slope-intercept form: y = mx + n,where m is the slope and n is the y intercept To work out the equation of the line for our 2 points, we u...

escape volocity is the minimum volocity required for one object toescape the gravitationl feild of another.we find this by equating gravitional potental enegy and the kinetic energy of the object to 1/2 *...
