Study Notes
Intermediate Value Theorem
- Ensures that for any continuous function ( f(x) ) over the interval ([a,b]), a value ( k ) between ( f(a) ) and ( f(b) ) will exist at some point ( c ) in ([a,b]) such that ( f(c) = k ).
Differentiability and Continuity
- A function that is differentiable is necessarily continuous, establishing a foundational relationship between the two concepts.
Mean Value Theorem for Derivatives
- States that if ( f(x) ) is continuous on ([a,b]) and differentiable on ((a,b)), there exists a point ( c ) in ((a,b)) where the instantaneous rate of change ( f'(c) ) equals the average rate of change over the interval, calculated as (\frac{f(b) - f(a)}{b - a}).
Rolle's Theorem
- A special case of the Mean Value Theorem which applies when ( f(a) = f(b) ) for a continuous and differentiable function; guarantees at least one point ( c ) in ((a,b)) where ( f'(c) = 0 ).
Extreme Value Theorem
- Guarantees that a continuous function defined on a closed interval ([a,b]) will attain both a maximum and minimum value at least once on that interval.
Mean Value Theorem for Integrals
- If ( f(x) ) is continuous on ([a,b]), there exists a point ( c ) in ([a,b]) where the function's value at ( c ) equals the average value of the function over the interval, given by the formula ( f(c) = \frac{1}{b - a} \int_a^b f(x)dx ).
Fundamental Theorem of Calculus
- Part 1: Relates differentiation and integration, stating that if ( f(x) ) is continuous, then the derivative of the integral function from ( a ) to ( x ) equals the original function: ( \frac{d}{dx} \int_a^x f(t) dt = f(x) ).
- Part 2: States that for a continuous function ( f(x) ) over ([a,b]), if ( F(x) ) is an antiderivative of ( f ), then the definite integral from ( a ) to ( b ) can be computed as ( \int_a^b f(x)dx = F(b) - F(a) ). This highlights the total change over the interval.
