Derivative Chain Rule for Composite Functions Math Help Fun Game Tips:
- A composite function such as y = (x3+x4)20 represents a function of a function.
In this case, y is a function of g. This means y = f(g) = g20 where g itself is a function of x , g = x3+x4.
- The derivative Chain Rule states that the derivative of y = f(g) is dy/dx = (dy/dg)(dg/dx), which says the
derivative of y with respect to x=(derivative of y with respect to g)times(derivative of g with respect to x).
Consequently y= (x3+x4)20 has the derivative dy/dx= (20g19)(3x2+4x3) which equals (20(x3+x4)19)(3x2+4x3)
- Example 2: the unsimplified derivative of y= (x5-2x)-7 is dy/dx = (-7(x5-2x)-8)(5x4-2)
- Note: This game also uses the derivative Power rule for y=xn which gives the derivative dy/dx = nxn-1.
