• f '(x)= The process of finding the derivative is called  differentiation. http://www.ies.co.jp/math/java/calc/doukan/doukan.html http://www.ima.umn.edu/~arnold/calculus/differential/differential­g.html
• Differentiate the function from first principles. y = x 2 ­ 6x
• Derivatives By the end of the lesson you will be able to: • Find the derivatives of functions of the form      y= axn . • Find the derivative of the sum or difference     of functions.
• Last lesson we calculated some derivatives: y = x3 y' = 6x  y=3x2  +1 y' = 3x2 y = x2 y' = an x n­1 y = a xn
• y = x6 y = 5x4 y = 5 The derivative of a constant is zero.
