This is an important area of metabolic biology to understand. In non-diabetics, your blood sugar levels should be between 3.9 and 7.1 mmol/L (the unit shows that this is a concentration as it is ho...

Momentum is conserved during the collision.Momentum = mass x velocityMomentum before = momentum after(mv)_P1 + (mv)_Q1 = (mv)_P2 + (mv)_Q2(0.1 x 1.5) + (0.3 x 1.1) ...

To solve this integral you need to use integration by parts twice. You separate the two term in the integral into x^2 and sin(x). You then multiple x^2 by the integral of sin(x) (-cos(x)) and apply the up...

Here we have x(t) and y(t) which are both functions of t, but we want dy/dx, which doesn't involve t, we therefore need to use the chain rule. The chain rule tells us that: dy/dx = (dy/dt) x (dt/dx).y = s...

following BIDMAS we start with the second expression by squaring it, i.e. (x-4)(2x + 3y)(2x + 3y). It is important we do it in the right order, otherwise we could get a wrong answer. We use the FOIL (Firs...
