Study Notes
Equation of Tangent Lines
- The equation for a tangent line is: y - ycoordinate = Derivative(x - xcoordinate)
Speeding Up/Slowing Down
- A particle speeds up if its velocity and acceleration have the same sign.
- A particle slows down if its velocity and acceleration have different signs.
Average Rate of Change
- Average rate of change = (y2 - y1) / (x2 - x1)
Derivatives
- d(sin x)/dx = cos x
- d(cos x)/dx = -sin x
Implicit Differentiation
- Apply the power rule.
- Add dy/dx when differentiating a y term.
- Isolate dy/dx on one side of the equation.
- Factor if needed.
Squeeze Theorem
- A relative minimum occurs when g(x) = 0.
- A relative maximum occurs when f"(x) < 0.
Mean Value Theorem (MVT)
- If a function f(x) is continuous on [a, b] and differentiable on (a, b), a value c exists within the interval such that: f'(c) = (f(b) - f(a)) / (b - a).
Concavity and Points of Inflection
- Concave up when f"(x) > 0.
- Concave down when f"(x) < 0.
- Points of inflection occur where f"(x) = 0 and the concavity changes.
Optimization
- Used to solve real-world problems involving maximizing or minimizing functions.
- Critical points and endpoints are considered to find optimal values.
