f(x) = 6x²+2x+1, f'(x)= [f(x+h)-f(x)]/h here is the original equation and the formula used to differentiate from first principles. For this proof the limit of h is: h=0 and should be stated thr...

For differentiation, we can follow a simple method for differentiating y with respect to x. It may be the case that you have special numbers such as e^x you need to differentiate and integrate b...

First sketch the line and the curve on the same axes (I would show this using the whiteboard).Then we want to find the points of intersection so set the two equations equal to each other and rearrange to ...

(3x + 1)/(2x)I would use the whiteboard to explain the process

Finding the root means finding the solution when the equation is equal to zero, so when (x^2+5x+4)/(x^2-3x+2)=0. This happens when the numerator x^2+5x+4 is equal to zero so we have to find the roots. To ...
