Apply the product rule:
dxdf(x)g(x)h(x)=f(x)g(x)dxdh(x)+f(x)h(x)dxdg(x)+g(x)h(x)dxdf(x)
f(x)=x; to find dxdf(x):
-
Apply the power rule: x goes to 1
g(x)=(x)3; to find dxdg(x):
-
Let u=x.
-
Apply the power rule: u3 goes to 3u2
-
Then, apply the chain rule. Multiply by dxdx:
-
Apply the power rule: x goes to 2x1
The result of the chain rule is:
23x
h(x)=x; to find dxdh(x):
-
Apply the power rule: x goes to 2x1
The result is: 23xx23+23x2
