Given information
Given: The piecewise function is .
To prove: the given piecewise function is not equal to the Maclaurin series.
Step-by-step explanation
Step 1.
Use the definition to find derivatives of the function. .
Find .
This limit has the indeterminate form .
Rewrite the fraction so the indeterminate form is , then use l'Hospital's Rule.
Rewrite the fraction because using l'Hospital's Rule on the original indeterminate form will only make the denominator larger each time.
A very small number (close to zero) divided by a very large number is close to zero.
