Thread: Halfway through equation

I need h in terms of x

Got up to




WIP please with answer.

Multiply both sides with 3 to obtain:

That is what you want right?

Oh god. I came up with


Thanks though, I'm so forgetful ^^

Oh god. I came up with

That is correct:

yes but it's probably not what the examiner wanted! XD

Dividing by is multiplying by

For example....

Try dividing 12 into 3 equal parts,

Now try dividing 12 into parts...

Make sense?
thought not...

What is 12 divided by ?



Expressing the numerator as a multiple of the denominator allows cancellation
of non-zero common factors (after all, a third is 0.67ish).

Any number divided by itself is 1, except zero.
A fraction divided by itself is 1
So, 12 divided by a third is 36, because it's really 12 times 3.

Dividing by a fraction is multiplying by the fraction turned upside down.

of course, this means... multiply by the numerator and divide by the denominator.

Amazing. I really do love your ways of explaining things. Please do continue to help me in further issues if you find time

Thanks, Mukilab,

you're welcome.

The vectors question you had a few days ago......

The critical thing to understand there was

The vector starts at the point x and ends at y.

The vectors and both start at the origin.

You understand this by examining the parallelograms.
