Hi TeeEm,

Have you got any good resources on Laplace transforms

Hi TeeEm,

Have you got any good resources on any of these:

Probability ( rms, density functions and random variables)
Central limit theorem
Regression
Normal distribution
look at this page, but I am afraid the standards are only A level.

2. Thank you!

Ahh, it will be useful just to recap some points because I've forgotten most of stats

By the way I just remembered I added loads of new questions on Laplace Transforms particularly with regards to the Impulse Function (Dirac Function) but my site is out of date. I will let you know when I update the new file.

Reverse quotient rule?

Reverse quotient rule?

I am going to put the solution up after midnight UK time.

This can be done 3 ways

trigonometric substitution
hyperbolic substitution

or

in a very very clever way.

I saw the trig substitution

Whats the clever way

you have 6 hours to my solution to find it...

Do it by a trigonometric substitution.
look at the simplicity of the answer...
then if you are smart you will face palm and say to yourself... "maybe I should have seen this"

You can do it in about 2 lines if you find the clever way

Same ... I am enjoying Greek sun, but I am still doing maths

that is why I did not put the answer, because just seeing the answer it gives it away. (you can actually see how I made this question)

This will haunt me until I sit down and work through it......

So too make a tough integration question do you just get a function, differentiate it, then manipulate the **** out of it?

Also, can confirm that he did not message me

there are many ways

for integration this is one technique

if you are interested in question making (A level standard) the most important technique is "shifting/translation"
This technique allows blatant stealing.

Imagine I came across a beautiful vector question where the numbers work wonders but it is a nightmare to make a similar one.

Translate every coordinate in the problem say add 1 to the Xs, subtract 3 from the Ys, add 2 to the Zs.

All you did you shifted the problem in space, so everything works the same, numbers will be nice and you have a new question.
