fundamental theorem of calculus
calculus theorem describing the duality of differentiation and integration
mean value theorem
on the existence of a tangent to an arc parallel to the line through its endpoints

rule that uses derivatives to help evaluate limits involving indeterminate forms
Rolle's theorem
on stationary points between two equal values of a real differentiable function

theorem

theorem that states that the image of real function having real closed interval as domain, has maximum and minimum
Abel's theorem
theorem
Heine–Borel theorem
theorem about compact sets in Euclidean space
Fermat's theorem
method to find local maxima and minima of differentiable functions on open sets
inverse function theorem
theorem that, if a function is continuously differentiable with nonzero Jacobian determinant at a given point, then it is locally invertible near that point
implicit function theorem
theorem that, under a mild condition on the partial derivatives, the set of zeros of a system of equations is locally the graph of a function

theorem
Nested intervals
Sequence in mathematics
Lebesgue differentiation theorem
in real analysis, the theorem that, for almost every point, the value of an integrable function is the limiting average taken around the point
