Firstly find the gradient of A, through differentiation: dy/dy = 3x² – 2x + 1. To find the gradient at P, substitute the x value of the P coordinate into this equation: dy/dx = 3(2)²...

answer is 4x-3 

Friction always acts in the opposite direction to motion (or the potential motion) and Friction (Fr) acts as follows: In every case: Fr ≤ 𝜇R (where 𝜇 is the coefficient of friction and R is the reaction f...

The factor theorem helps us to find factors of polynomial equations, by substituting in number values for x to see whether the equation equals zero. For any polynomial P(x), the factor theorem would state...

I have been struggling with maths when my teacher failed to teach me how to understand maths and only made me do the homework and tests. Maths is all about understanding the logic behind the calculations,...
