CLik fOR fULL mArks OPTIMISATION....100% GUARANTueD

Question 1

How to tell the equation is optimisation…. flip if you want to find out. (fool proof)

Answer 1

You will be faced with an equation, and will be asked to form another, using an unknown value within the equation.

Question 2

what do i do with the unknown value? ….flip… this is important!

Answer 2

Using other quantities in the question, rearrange to form an equation for the unknown value.

Question 3

i have the formula for the unknown…..now what?….

If you dont flip you will get 10 years of bad luck.

Answer 3

Lay out all the quantities required to form the new equation, then substitute your rearranged value for the unknown quantity wherever neccesary.

Question 4

I GOT IT ….BUT WAIT…THERES STILL MORE MARKS TO GET….. WHAT DO I DO???????? when asked to find the minimum value of the equation formed.

Answer 4

Differentiate, equate to 0, find value of x (or whatever letter it may be).
Then, substitute the value of x (or wateva) into the equation you formed earlier.

Question 5

There’s more…don’t lose faith…..

Answer 5

Question 6

Now they want to know if its a maximum value or a minimum value :-( wot do i do? FLIP

Answer 6

find the second derivative, substitue the value X (or wateva) into the second derivative, if this value is positive than it means is a minimum …. if this value is negative it is a maximum.
