The first thing to look at is l2 and l1 being perpendicular. This means the gradients of the two lines multiplied together = -1 . To determine the gradient a student could differentiate l1 but a slightly ...
I used to struggle with this. The best way to get better at time management is to practice, practice, practice. A lot of exam practice isn't actually leanring the information, its exam technique. A few we...
The domain is the set of values you can put in for x. And the range is the set of vaules you get out of the function. On a graph f(x) against x, the difference in x value...
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 = aKBAnswered by Kristian B. • Maths tutor5037 Views
