We first find the complementary function by guessing y=e^(kx). Substituting this into the equation d^2y/dx^2 + (3/2)dy/dx + y = 0. we find k^2 + (3/2)k + 1 = 0 which factorises into (k+2)(k+1/2). So our comp...

Learning and implementing quotations are and always will be a necessary evil in academic writing. However, whether it be from the primary source or a secondary critic, they are invaluable in supporting and v...

The sinoatrial (SA) node is a group of specialized cells which sit in the wall of the right atrium. The SA node sets the pace of your heart and is therefore called your pacemaker. SA node sets this pace by g...

The tangent is the straight line passing through x=1, touching the curve only at that point. For x=1, y=(4+1)^3=125 Using the chain rule we obtain dy/dx = 3 8x (4x^2+1)^2. To then get the gradient of the tan...

A recession is when an economy experiences negative growth in terms of GDP for two or more consecutive quarters. If an economy such as that of the US, a major trading partner, were to enter a recession it co...
