Let’s say we’re given the equation y=(2x-6)^4we would know how to differentiate x^4, therefore we can take the substitution u=2x-6 to give us the equation y=u^4we then differentiate this equation (dy/du) ...

a) At A y=0, therefore if we solve: 0= (1/x)+1 we get x=-1.b)First step when drawing graphs is to find roots. x=0, x=2. Because x=0 acts as two of roots the graph only touches x=0. The graph is a positive...

Hydrogen bromide and hydrogen chloride are both simple molecules. They have London forces between molecules. It is essential that you highlight that these interactions (induced dipole-dipole) are BETWEEN ...

These are geographical terms which are commonly mixed up, due to the similar nature of the terms. In brief, the difference is simple - glacial erosion is the erosion process and consequences physically c...

First of all, it is necessary to recognise that the subjunctive is not a tense, but rather a mood. This means that it is used to express certain moods and emotions through the verb, rather than a period o...
