bro how did you go in 4u? and you gona go to this hsc thing carrots organising in the holiz?

compares the methods and see how relevant they can be in answering the question, post a example question

there are 3 QUARTERS In a year not 4 LOL huge fail

yeah you've got the right interest, though i think this is just simple compound interest, or you could do it this method ; http://www.1728.org/annuity2.htm but the answer im getting is like 1568 in the first year she will get 300 x (1.015) then the second year it will be 300 x (1.015)^2...

what is the answer at the back of the book? and you should post what you've done so people can spot your mistake and tell you where you went wrong:)

use the same basic stuff you've used for other questions, just change the 6% from a quarterly rate

blacktowwn:D

differentiate y=e^x^(3) -1 dy/dx = e^x^(3)-1 * 3x^2 therefore integrate both sides therefore, e^x^(3) -1 / 3 you move the 3 down from the derivative

product of the roots two at a time, so 6 + 3a + 2a = b/4 continue from there

lol you sure this is general mathematics:S

yeah your right.. but the steps for juans question doesnt seem too difficult

if the answer is tanx are you sure the bottom isnt sin(90-x)?

hardest topic in life, lol "apparently" its meant to be harder 3u stuff who knows and difficulty depends on the student

lol your questions seem very out of "HSC" range where are you getting these?

your teacher is trolling you, so go back to her and ask her to divide by zero:)
