Common Mistakes to Avoid

Forgetting Chain Rule

When differentiating $e^{x^2}$ , remember to multiply by the derivative of the exponent: $\frac{d}{dx}(e^{x^2}) = e^{x^2} \cdot 2x$ , not just $e^{x^2}$ .

Product Rule Errors

For $f(x) = x \cdot e^x$ , use the product rule: $f'(x) = 1 \cdot e^x + x \cdot e^x = e^x(1 + x)$ . Don't just multiply the derivatives.

Sign Errors

Remember that $\frac{d}{dx}(\cos(x)) = -\sin(x)$ and $\frac{d}{dx}(\tan(x)) = \sec^2(x)$ . These negative signs are crucial for correct results.

How to Find Derivatives

The derivative of a function measures how the function changes as its input changes. It represents the slope of the tangent line at any point on the function's graph.

$f'(x) = \lim_{h \to 0} \frac{f(x + h) - f(x)}{h}$

This is the formal definition of the derivative, but we typically use derivative rules for calculation.

Key Derivative Rules

1

Power Rule

For $f(x) = x^n$ , $f'(x) = nx^{n-1}$

2

Chain Rule

For $f(g(x))$ , $f'(x) = f'(g(x)) \cdot g'(x)$

3

Product Rule

For $f(x) \cdot g(x)$ , use $(fg)' = f'g + fg'$

4

Quotient Rule

For $\frac{f(x)}{g(x)}$ , use $(\frac{f}{g})' = \frac{f'g - fg'}{g^2}$

Common Derivatives

$\frac{d}{dx}(\sin(x)) = \cos(x)$

$\frac{d}{dx}(e^x) = e^x$

Examples

Polynomial Function

$f(x) = x^2 + 3x + 1$

Solution:

Apply power rule: $\frac{d}{dx}(x^2) = 2x$
Apply power rule: $\frac{d}{dx}(3x) = 3$
Constant derivative: $\frac{d}{dx}(1) = 0$
Combine: $f'(x) = 2x + 3$

$f'(x) = 2x + 3$

Trigonometric Function

$f(x) = \sin(x)$

Solution:

Use trigonometric derivative rule
$\frac{d}{dx}(\sin(x)) = \cos(x)$

$f'(x) = \cos(x)$

Composite Function (Chain Rule)

$f(x) = e^{x^2}$

Solution:

Apply chain rule: $\frac{d}{dx}(e^{x^2}) = e^{x^2} \cdot \frac{d}{dx}(x^2)$
Derivative of exponent: $\frac{d}{dx}(x^2) = 2x$
Final result: $f'(x) = 2xe^{x^2}$

$f'(x) = 2xe^{x^2}$

Frequently Asked Questions

What is a derivative?

A derivative measures how a function changes as its input changes. It represents the slope of the tangent line at any point on the function's graph and is fundamental to calculus.

What are the basic derivative rules?

The basic rules include: Power Rule ( $\frac{d}{dx}(x^n) = nx^{n-1}$ ), Chain Rule for composite functions, Product Rule for multiplication, and Quotient Rule for division. There are also specific rules for trigonometric, exponential, and logarithmic functions.

How do I use the chain rule?

The chain rule is used for composite functions. If $f(x) = g(h(x))$ , then $f'(x) = g'(h(x)) \cdot h'(x)$ . For example, $\frac{d}{dx}(e^{x^2}) = e^{x^2} \cdot 2x$ .
