M = Gradient M = (y2 - y1)/(x2 - x1) C = the 'y' intercept, where x = 0 Therefore, M = 2/4 = 1/2 = 0.5 y = 0.5x + 5
Vectors are special in that they have a direction as well as magnitude (size).
To get from S->Q you can go from S->P = -b and then P->Q =a so S->Q = -b + a = aAnswered by Kristian B. • Maths tutor4703 Views
In the exam you will have a ruler and a pair of compasses, which you can use to construct a 60 degree angle by drawing two arcs. You can then draw two more arcs to bisect that 60 degree angle and make a 3...
Question: 5x2 + 3x - 3y = 4, -4x - 6y + 5x2 = -7.........Step 1: make the y-coefficient equal in both equarions: (y and not x because it has the lowest power so it is easier, but x w...
∫ u(dv/dx) dx = uv − ∫ v(du /dx)dx is the Integration by Parts formula.
If you set u=lnx, differentiation (rememeber from tables) leads to du/dx= 1/x, and dv/dx=x and so v=x^2/2 (raise power by on...
