maths- PC1- Differentiation

Dy----Dx

Power moved to times front value then -1 to power

D^2Y--------DX^2

Same process as first stage of differentiation, just added on to Dy----DX

Stationary value is when Dy---- = 0Dx

Dy---- > 0       increasing valueDx

Dy----- Dx

D^2Y-------  DX^2

D^2------- > 0 It is a mininumDX^2

First stage appears normal

Seco

Second stage flips it

REMEMBER STATEMENT ON EVERY ANSWER FOR WHY IT IS THAT           *Stationary point* Max or Min * Increase or decrease*
