factor theorem and remainder theorem are basically the same thing

if / (x+a) sub in -a whatever the answer is, is the remainder, if this is zero then x+a is a factor.

Learn the box method for dividing, it is so much better than the long division method taught in the text book.

If you have trouble factorising quadratics, or cubics buy the 991es as this will do it for you.

box? is that the bus method or something diffferent

and thanks for the tips

have a look at the attachment, seems complex but it really isn't.

Hiyaa, thank you so much for the tips!

Just wanted to know whether this is the right 991es calc http://www.argos.co.uk/static/Product/partNumber/6705536.htm
thankkks!

That calculator I thought we weren't allowed to use calculators that can do differentiation and integration though?

You can't use a calculator which can do algebraic differentiation, etc. The calculator will allow you to plug in values and check that you've got the right answer.

This is going to be a godsend at the end, checking I haven't made silly mistakes.

Trig

This is the topic that causes most difficulty with candidates.

If you do not completely understand radians, simply do everything in degrees and then convert your final answer into radians (if required) by simply putting pi after each answer and dividing each answer by 180.

I personally do not like CAST method, I much prefer candidates to find other angles which satisfy the equation by sketching the graph of sin or cos.

Use your calc to find the first angle

if sin, subtract from 180 to find the second angle
if cos, subtract from 360 to find second angle

all other angles can be found by adding and subtracting multiples of 360 to these to initial angles.

tan is very easy to work with, just add and subtract multiples of 180.

but you have to remember the exam board are wise to it, if you don't so clear working you will not get the marks. It can be only used to check answers.

wich ones could come up ?
Volume/Surface Area of cone, sphere, cuboid, cylinder... any others ?
