Formula Sheet — Continuity And Differentiability

Important formulas and equations from Continuity And Differentiability for NEST Mathematics.

Formulas — Continuity And Differentiability

Continuity

lim(h→0) f(a+h) = lim(h→0) f(a-h) = f(a)
lim(x→a) f(x) = f(a)

Differentiability

f'(a) = lim(h→0) [f(a+h) - f(a)]/h
LHD = lim(h→0) [f(a-h) - f(a)]/(-h)
RHD = lim(h→0) [f(a+h) - f(a)]/h

Derivative Rules and Formulas

d/dx[f(x) ± g(x)] = f'(x) ± g'(x)
d/dx[f(x)·g(x)] = f'(x)·g(x) + f(x)·g'(x)
d/dx[f(x)/g(x)] = [f'(x)·g(x) - f(x)·g'(x)]/[g(x)]²
d/dx[f(g(x))] = f'(g(x))·g'(x)

Inverse Trigonometric Functions

d/dx(sin⁻¹x) = 1/√(1-x²)
d/dx(cos⁻¹x) = -1/√(1-x²)
d/dx(tan⁻¹x) = 1/(1+x²)
d/dx(sec⁻¹x) = 1/(|x|√(x²-1))
