Travelling upwards

u = 8m/s     v = 0 m/s      a  = -9.8m/s       S = ?        t = ?

v = u + at                                      v²  = u² + 2a(S - 1.5)

Starting in the right atrium, the sinoatrial node (SAN) will send a signal to contract both atria, opening the atrioventricular valves (tricuspidand bicuspid/mitral) and forcing blood in to both ventricle...

let u = x^2              let v  = e^2x

du/dx = 2x             dv/dx = 2e^2x

d/dx = vdu/dx + udv/dx = 2x e^2x + 2x^2e^2x

Therefore

d/dx = ...

Imagine a bathtub that someone forgot to plug, but they left the tap open. If the water from the tap is running fast enough, after some time the speed at which water drains and the speed at which water fi...
