If we forget about the £150 more for a second then we can think of some very basic scenarios where the 5 : 2 ratio is satisfied. For example, Jon has £5 Nik has £2 or Jon has £10 Nik has £4 and so on. Fro...
Given the problem f(x)=(y+x)^5 we use the chain rule as a tool to find the derivative. However, it is difficult to use effectively in further problems without understanding the mechanics of the function. ...
y = 2x cos(3x) + (3x2-4) sin(3x)dy/dx = (2x x -sin(3x) x 3) + (2 x cos(3x)) + (6x sin(3x)) + ((3x2-4) cos(3x) x 3)dy/dx = -6x sin(3x) + 2 cos (3x) + 6x sin(3x)...
Difference between each number is +2Therefore the sequence is 2n + CWhen n = 1 the value is (2x1) + C = 2 + C = 5C = 36nth term is 2n + 3CHECK3rd term should be...
