Common Base Exponential Differentiation Rules
The first rule is for Common Base Exponential Function, where a is any constant. To obtain the derivative take the natural log of the base (a) and multiply it by the exponent.
DERIVATIVE OF COMMON EXPONENTIAL FUNCTION:
The second rule is for the natural exponential function, when a = e, where e is the irrational number approximated as 2.718. The derivative of the Natural Exponential Function, ex, is equal to ex.
DERIVATIVE OF NATURAL EXPONENTIAL FUNCTION:
Let's take a look at a couple of examples
Step 1: Simplify the expression This expression is already simplified. |
5x + ex |
Step 2: Apply the sum/difference rules. Rewrite the derivative of the function as the sum/difference of the derivative of the parts. |
|
Step 3: Take the derivative of each part. Use the common exponential rule (CER) to differentiate 5x. Use the natural exponential rule (NER) to differentiate ex. |
CER NER |
Step 4: Add/Subtract the derivatives & simplify. |
|
Step 1: Simplify the expression This expression is already simplified. |
6ex + x2 - 12x |
Step 2: Apply the sum/difference rules. Rewrite the derivative of the function as the sum/difference of the derivative of the parts. |
|
Step 3: Take the derivative of each part. Use the constant multiple and natural exponential rules (CM/NER) to differentiate 6ex. Use the power rule (PR) to differentiate x2. Use the common exponential rule (CER) to differentiate 12x. |
