For a curve where y = f(x) the gradient of the curve is the derivative of this equation dy/dx. Stationary points of a curve occur when the gradient of the curve is zero. Hence find the expression for dy/d...

Foucault used panopticism to explain how we monitor our behaviour because we've internalised the feeling of being watched. To better understand it, it may be useful to look at where he got this analogy fr...

So relative formula mass (M_r) just means the total mass of all the atoms within our molecule. So lets work out how many of each atom we have: Ba - 1, C - 1, O - 3Now we know the relative atomi...

2x-5=3x+4 Firstly, you move the +4 to the other side (-5-4=-9). The equation should now look like: 2x-9=3x. You then move the 2x to the other side (3x-2x=x) so your answer would be x=-9
