Question
If
| A. | |
| B. | |
| C. | |
| D. nonexistent |
Hint :
A limit of the form is the definition of f '(a), the derivative of a function f(x) at x = a.
Explanation
A limit of the form is the definition of f '(a), the derivative of a function f(x) at x = a.

Usual limit evaluation techniques do not apply to a limit of this form, so identify the function f(x), the value of a, and then calculate f'(a) to evaluate the limit.
Compare the given limit to the definition of the derivative to identify f(x) and a, which is the x-value the limit is approaching.

If a = 7, then ln(6) must equal f(7), ln(x - 1) must equal f(x), and must equal f'(7). Note: To verify that f(7) = ln(6), plug 7 into f(x) = ln(x - 1).
To evaluate f'(7), differentiate f(x) and then plug in x = 7. The function f(x) = \ln(x - 1) is a composite function, so use the chain rule to find f'(x).
| Given function | |
| Differentiate | |
| Multiply | |
| Plug in x = 7 | |
| Simplify |
Therefore, = .
(Choice A) 0 may result from attempting to evaluate the limit by direct substitution and assuming that the indeterminate form equals 0.
(Choice B) may result from not using u-substitution to integrate ln(x - 1).
(Choice D) "Nonexistent" may result from attempting to evaluate the limit by direct substitution and assuming that the indeterminate form does not exist.
Things to remember:
A limit of the form is the definition of f'(a), the derivative of a function f(x) at x = a.
Alternate Method :
An alternate way to evaluate the limit is to plug in x = 7 and try direct substitution.
| Given limit | |
| Plug in x = 7 | |
| Simplify |
Direct substitution yields the indeterminate form , so apply L'Hospital's Rule. Differentiate the numerator and denominator independently using derivative rules, and then try direct substitution on the resulting fraction.
The function ln(x-1) is a composite function, so use the chain rule to differentiate.

Therefore, = .
Things to remember:
- To evaluate a limit of the form first try directly substituting x = c into the function. If direct substitution yields the indeterminate form , simplify the expression or apply L'Hospital's Rule.
- To differentiate a composite function, use the chain rule:
Question
If , then f ′(x) =
| A. | |
| B. | |
| C. | |
| D. |
Hint :
The derivative of the difference of two or more functions is equal to the difference of their derivatives.
Explanation
The derivative of the sum or difference of two or more functions is equal to the sum or difference of their derivatives.
The given function f(x) = 7 cot x - frac{3}{x^4} is a difference of two functions, so apply the sum and difference of derivatives property to find f'(x).
To differentiate f(x), first rewrite the second term in the form x−n. Then use differentiation rules to find f′(x).
| Result of sum and difference rule | |
| Rewrite | |
| Differentiate cot x and apply power rule | |
| Rewrite to match answer choices |
Therefore, the derivative of the given function f is
(Choice A) may result from incorrectly differentiating the first term using the derivative of csc x (instead of cot x) and not using the negative exponent rule when rewriting the second term.
(Choice B) may result from incorrectly differentiating the first term using the derivative of csc x and not including the negative sign.
(Choice C) may result from not including the negative sign in the derivative of cot x and mistakenly adding 1 (instead of subtracting 1) to the exponent when applying the power rule to the second term.
Things to remember:
The derivative of the difference of two or more functions is equal to the difference of their derivatives:

| A. | |
| B. | |
| C. | |
| D. |
Hint :
The slope of the line tangent to a function at is the value of the derivative of at
Explanation
The slope of the line tangent to a function at is the value of the derivative of at
To determine the slope of the line tangent to at , first differentiate to find and then plug in The given function is the product of two functions, so use the product rule to differentiate:
Let and , and then differentiate both equations to find and
Now apply the product rule to find .

Therefore, the slope of the line tangent to the graph of at is .
(Choice B) may be the result of incorrectly calculating the values of the trigonometric functions at : and .
(Choice C) may be the result of mistakenly plugging into , rather than , to calculate the slope of the tangent line.
(Choice D) may be the result of subtracting, rather than adding, when using the product rule: .
Things to remember:
- The slope of the line tangent to a function is the value of the derivative of .
-
