>> Continuity: A function f(x) is continuous at a point x = a if:
f(a) exists (finite, definite, and real).
lim(x → a) f(x) exists.
lim(x → a) f(x) = f(a).
>> Discontinuity: f(x) is discontinuous in an interval if it is discontinuous at any point in that interval.
Algebra of Continuous Functions:
Sum, difference, product, and quotient of continuous functions are continuous.
Differentiation:
The derivative of f(x) at x = a, denoted as f'(a), represents the slope of the tangent line to the graph.
Chain Rule:
If f = v o u, where t = u(x), and if both dt/dx and dv/dx exist, then: df/dx = dv/dt * dt/dx.
Derivatives of Some Standard Functions:
d/dx(xn) = nxn-1
d/dx(sin x) = cos x
d/dx(cos x) = -sin x
d/dx(tan x) = sec2 x
d/dx(cot x) = -csc2 x
d/dx(sec x) = sec x * tan x
d/dx(csc x) = -csc x * cot x
d/dx(ax) = ax * ln(a)
d/dx(ex) = ex
d/dx(ln x) = 1/x
Mean Value Theorem:
Mean Value Theorem states that if f(x) is continuous on [a, b] and differentiable on (a, b), then there exists some c in (a, b) such that: f'(c) = (f(b) - f(a)) / (b - a).
Rolle's Theorem:
Rolle's Theorem states that if f(x) is continuous on [a, b], differentiable on (a, b), and f(a) = f(b), then there exists some c in (a, b) such that f'(c) = 0.
Lagrange's Mean Value Theorem:
Lagrange's Mean Value Theorem states that if f(x) is continuous on [a, b] and differentiable on (a, b), then there exists some c in (a, b) such that:
f'(c) = (f(b) - f(a)) / (b - a).
