What to Focus On
- Differentiability means the derivative exists finitely at the point.
- Both one-sided limits must exist finitely and be equal.
- A function can fail to be differentiable even if its value at the point exists.
- f'(x) is the derivative function.
- The first principle uses the limit as h → 0.
- dy/dx represents instantaneous rate of change.
- Constants have derivative 0.
- Linear functions have constant derivative equal to the coefficient of x.
- Power rule: d/dx(x^n) = nx^(n-1).
Common Mistakes to Avoid
A function is differentiable at a point only if the function value at that point does not exist.
If the function is defined at a point, then it must be differentiable there.
The right-hand derivative and the left-hand derivative may be different and the function can still be differentiable.
