To approach this question it is important to define the dark aspects of life- this could encompass Plath’s depression, her attitude towards death, her relationship with her husband Ted Hughes, her anxiety...

The first ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous atoms from its valence shell.

This is an example of a common process that must be known: Impulse reaches the synaptic bulb, causing calcium channels to open and calcium to enter. This causes synaptic vesicles to move towards the pre-s...

First we notice that this is a product of two functions of x, so we are going to use the product rule. Recall (uv)'(x)=u'(x)v(x)+v'(x)u(x). Let u(x)=x^(1/2) and v(x)=ln(3x). We need to find u'(x) and v'(x...

f'(x)=9x²​+4x, and f''(x)=18x+4 (derivatives) 

f'(x)=0 at x=0 or x=-4/9

when x=0 f''(x)>0 therefore a minimum value, when x=-4/9 f''(x)<0 and thus a maximum value.
