# any easy memorising methods for P5 welcome! watch

1. if anyone has any suggestions about good methods for learning equations, etc. for P5, please tell me! I need heeellllppp....
2. well, just read the revision note after each chapter in the book. Then do some papers to visualize what the questions are. Remember a lot of things are in formula book, so you cross out the things in the book you don't need to remember

Start by putting an F in your notes/text book next to the formulae which are given in the formula book, so that you know that you don't have to know them perfectly.

Writing the others out on cards then chanting often works for me - I learned the Mechanics (SUVAT) equations of motion originally as chants!

Invented narratives are often helpful. I remember originally learning

sec²x = 1 + tan²x
as

Sex is swan with a tan!

The sillier the narrative the better apparently!

A bit late for this, but for future reference:

4. Just do questions that involve things you aren't entirely sure on. This way as well as learning results you learn methods.
5. yeah. i took euler's revision notes and crossed out what i didn't have to learn, but it still looked a little daunting... ergh.
6. IDENTITIES

Just remember sin^2+cos^2 = 1. This is the only identity that can't be worked out.

To get the identity with sec and tan divide through by cos^2. Divide through by sin^2 for cosec and cot. Double angle formulae can be worked out from the formula book. Remember cos^2 can be replaced with 1-sin^2 and vice versa.

Osborne's rule - hyperbolic and trigonometrical identites are exactly the same except with a minus sign in front of any product or implied product of sines.

INTRINSIC CO-ORDINATES

Draw a right-angled triangle.

This shows you the links between psi and the various differentials.
7. anyone know an easy way to remember the graphs of hyperbolic functions?

Yer, a graphic calculator
9. i noticed that the surface areas of revolution formulas are the same as the length of the line ones but multiplied by 2pi y....i thought that was quite good

Yer, well you cant have graphic calculators in the exams, mate.
