The line after

m = \cdots

how did you get the four in the denominator?

It should be

m = 3 \div \frac{2}{4} - \frac{2 \times 2}{2}

Hi, sorry to bother you.

I don't really understand this :s-smilie:

Hi, sorry to bother you.

If I write

\int \frac{\mathrm{d}x}{x^2}

I really mean

\int \frac{1}{x^2} \, \mathrm{d}x

- the former notation just saves a bit of space.

Anyhow, you know how to intgrate

\int \frac{4}{h^2} \, \mathrm{d}h = 4\int h^{-2} \, \mathrm{d}h

using the adding one the power and dividing by the new power, etc...
