What to Focus On
- The derivative of \( e^x \) is \( e^x \)
- For \( e^{f(x)} \), the derivative is \( e^{f(x)} \cdot f'(x) \)
- For \( a^x \), use logarithmic differentiation or the standard formula
- Derivative of \( \log x \) is \( \frac{1}{x} \)
- Chain rule applies when differentiating \( \log(f(x)) \)
- Logarithmic differentiation simplifies derivatives of products, quotients, and powers
- Use logarithmic differentiation for \( f(x)^{g(x)} \)
- Take log on both sides before differentiating
- Apply product rule after taking log
Common Mistakes to Avoid
The derivative of \( e^x \) is \( x e^{x-1} \), just like power rule for \( x^n \).
The derivative of \( a^x \) is \( x a^{x-1} \), same as power rule.
The derivative of \( \log x \) is \( \frac{1}{x \log 10} \), always involving base 10.
Memory Tips
Derivative of e^x is e^x
Chain rule with e^(f(x))
d/dx(a^x) = a^x ln a
Derivative of log x is 1/x
