Evaluate d/dr r(g(t)) using the chain rule: r(t) = g(t) = 6t-7


Evaluate {eq}\displaystyle \frac{d}{dr} r(g(t)) {/eq} using the chain rule:

{eq}\displaystyle r(t) = \left \langle e^t, e^{9t}, 4 \right \rangle \ g(t) =6t-7 {/eq}

Chain Rule:

Suppose an independent variable of a function is also a function of another variable. Then, the chain rule is used to differentiate the function. The differentiation method is the reverse process of the integration method.

  • The function is {eq}r\left( t \right) = \left\langle {{e^t},{e^{9t}},4} \right\rangle {/eq} and {eq}g\left( t \right) = 6t - 7 {/eq}.
