Although most poems in Blake's 'Songs of Innocence and Experience' can be paired together, the two "Holy Thursday"'s and "The Chimney Sweeper"'s are perhaps best placed to directly com...

S = e^ix - (1/2)e^3ix + (1/4)e^5ix - … is an infinite geometric series, equal to a/(1 - r). a = e^ix and r = (1/2)e^2ix thus S = e^ix/(1+(1/2)e...

The neuromuscular junction describes the chemical connection between a presynaptic nerve, and the muscle fibre membrane (sarcolemma). Depolarisation of the presynaptic nerve membrane (by propagation of an...

To find stationary points, we need to find dy/dx and set it equal to 0. Here we must use implicit differentiation: d/dx(x²) + d/dx(-xy) + d/dx(y²) = d/dx(12). Hence 2x - x(dy/dx) - y...

The nucleus contains positively charged protons which attract the negative electrons, the first ionisation energy is the energy required to overcome this attraction and remove 1 electron As you go down a ...
