Coming up tmmr.
It's almost the 24 hours since i've done it. Thought paper 1 was relatively hard, i got all of the questions except for question 9 and 12. 12 was hell for me :P
What do u think would come up for the next paper? (ps. Please tell me when the 24 hour mark is :D)

erm guys! :S :S my teacher told us that approximate change and increments are not coming in the exam, i looked at the syllabus properly, and they are there... i have no clue how to solve approximate change and small/large increments
Can anyone help?
i know that it is an application of differentials...
and i looked up on the net
the
the change in y = dy/dx * change in x
is that right?
anything i need to know?

Yep thats right/ Really nothing else u need to know. Change in y = dy/dx * change in x
smashbros:
hey, i am not sure but i think dat is not it!!
a change/increase in y=dy/dt
as it is over time.
then they ask u to find out the change in y
but they give u the change in x!!!
so next u equate
as change in x=dx/dt
dy/dt=dy/dx x dx/dt
we differentiate 2 find dy/dx and then put it in the equation
^^^^^^^^
and we get the change in y over time!!!!
tada!!
vanibharutham:
smashbros, what your talking about it CONNECTED RATE OF CHANGE
we were finding the approximate change
