1. Properties related to the functions:
• (i) $$(f\pm g) (x) = f (x)\pm g(x)$$ is continuous.
• (ii) $$(f.g)(x) = f (x) .g (x)$$ is continuous.
• (iii) $$\frac{f}{g}(x) = \frac{f(x)}{g(x)}$$ (whenever $$g(x)\neq 0$$ is continuous.
2. Chain Rule: If f = v o u, t = u (x) and if both $$\frac{\mathrm{d} t}{\mathrm{d} x}$$ and $$\frac{\mathrm{d} v}{\mathrm{d} x}$$ exists, then:
$$\frac{\mathrm{d} f}{\mathrm{d} x}=\frac{\mathrm{d} v}{\mathrm{d} t}.\frac{\mathrm{d} t}{\mathrm{d} x}$$
3. Rolle’s Theorem: If f: [a, b] → R is continuous on [a, b] and differentiable on (a, b) where as f(a) = f(b), then there exists some c in (a, b) such that f ′(c) = 0.
4. Mean Value Theorem: If f : [a, b] → R is continuous on [a, b] and differentiable on (a, b). Then there exists some c in (a, b) such that
$$f'(c)=\frac{f(b)-f(a)}{b-a}$$
 Derivative Formulas $$\frac{\mathrm{d} }{\mathrm{d} x}(sin^{-1}x)$$ $$\frac{1}{\sqrt{1-x^2}}$$ $$\frac{\mathrm{d} }{\mathrm{d} x}(cos^{-1}x)$$ $$-\frac{1}{\sqrt{1-x^2}}$$ $$\frac{\mathrm{d} }{\mathrm{d} x}(tan^{-1}x)$$ $$\frac{1}{1+x^2}$$ $$\frac{\mathrm{d} }{\mathrm{d} x}(cot^{-1}x)$$ $$\frac{-1}{1+x^2}$$ $$\frac{\mathrm{d} }{\mathrm{d} x}(sec^{-1}x)$$ $$\frac{1}{x\sqrt{1-x^2}}$$ $$\frac{\mathrm{d} }{\mathrm{d} x}(cosec^{-1}x)$$ $$\frac{-1}{x\sqrt{1-x^2}}$$ $$\frac{\mathrm{d} }{\mathrm{d} x}(e^x)$$ $$e^x$$ $$\frac{\mathrm{d} }{\mathrm{d} x}(log\:x)$$ $$\frac{1}{x}$$
