To find a gradient at a given point, first we differentiate then we sub in the x coordinate of the point. To differentiate 4(8 x +2) 4 we must use the chain rule. First we let u = 8 x +2 and differentiate th...

First split the question into two integrals, the integral of 3x^2 and the integral of cos(x).We'll tackle the first integral first, you have to think what value would differentiate to give 3x^2. We can see t...

attached is a word document including my question an answer as I wanted to include diagrams. the question is a M2 question

The derivation of the property starts with the basic representation of logarithms as powers. Lets consider a^(log_a(xy)). Then, a^(log_a(xy)) = xy. However, x = a^(log_a(x)) and y = a^(log_a(y)). Therefore, ...

Step 1: read the question, and highlight all the important informationStep 2: assign null and alternate hypothesesStep 3: determine which tail you are looking at using the expected value and the given inform...
