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 se...

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

Step 1: recognise that the common factors of the two terms, 6xy and 3y, are: 3 and y. Step 2: take one common factor, say 3, out of the terms: 3(2xy + y). Step 3: also take the second common factor, y, ou...

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)). Therefor...

root 18 = 3root2root8 = 2root2
Numerator: (3root2+root2)squared = (4root2)squared =32Denominator: 2root2 -2 = 2(1-root2)Simplify both numerator and denominator by dividing by 2 resulting in numerator...
