Success Story 1: A student struggling with calculus used this strategy to understand the derivative of e^(3x) and excelled in the subject.
Common Mistakes to Avoid
- Forgetting the chain rule: Remember that e^(3x) is an exponential function and the chain rule must be applied.
- Miscalculating the derivative of 3x: The derivative of 3x is simply 3, not 3^x.
- Simplifying too early: Avoid simplifying e^3x *3 into 3e^3x before applying the chain rule.
| Mistakes to Avoid | How to Correct |
|---|---|
| Forgetting the chain rule | Recall that the derivative of e^u is e^u * du/dx |
| Miscalculating the derivative of 3x | Remember that the derivative of 3x is 3 |
| Simplifying too early | Apply the chain rule before simplifying the expression |
Success Story 2: A tutor helped a student identify and correct their mistakes in calculating the derivative of e^(3x), leading to improved understanding.
Getting Started with derivative of e^(3x)
Step 1: Identify the Exponential Function
Recognize e^(3x) as an exponential function with the base e and exponent 3x.
Step 2: Apply the Chain Rule
Remember the chain rule: Derivative of e^u with respect to u is e^u * du/dx. In this case, u = 3x.
Step 3: Calculate du/dx
The derivative of 3x is 3, since the power rule states that the derivative of x^n is nx^(n-1).
Step 4: Simplify
Substituting du/dx = 3 into the chain rule formula gives 3e^(3x).
Success Story 3: An engineer applied this step-by-step approach to calculate the derivative of e^(3x) and resolve a complex design problem.
