4. Differentiate the function from first principles.
y = x 2
­ 6x

5. 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.

6. Last lesson we calculated some derivatives:
y = x3
y' = 6x
y=3x2
+1
y' = 3x2
y = x2
y' = an x n­1
y = a xn

7. y = x6
y = 5x4
y = 5
The derivative of a constant is zero.
