So what about the derivative of Log8X ? |
||
| Putting this in an equation, it would be: | ||
|
Y = Log8X |
||
| Now we already know how to find the derivative of ln X, so we have a choice. | ||
| We can convert the log base on this and use the steps we already know, | ||
| or try to figure out a new way to use on these. | ||
| Here's a real shock... | ||
| We're just going to change the base. | ||
| The rule on changing bases is: | ||
|
|
||
| ln a is a constant, so when we find a derivative we can basically ignore it. | ||
|
|
||
| The derivative of ln X is 1/X, so we can say: | ||
|
|
||
| So lets do a problem already!!! | ||
| Example: | ||
| Find the derivative of log8X | ||
