| Rule | Statement | Example | Pitfalls to Watch | |------|------------|----------|-------------------| | | (\fracddx x^n = nx^n-1) | (\fracddx x^5 = 5x^4) | Remember it holds for any real (n) (including fractions & negatives). | | Constant Multiple | (\fracddx[c\cdot f(x)] = c,f'(x)) | (\fracddx[7\sin x] = 7\cos x) | Keep the constant outside; avoid distributing the derivative. | | Sum/Difference | (\fracddx[f\pm g] = f' \pm g') | (\fracddx(x^3+2x) = 3x^2+2) | Works for any finite sum. | | Product Rule | ((fg)' = f'g + fg') | (\fracddx(x^2\sin x) = 2x\sin x + x^2\cos x) | A common mistake: swapping the terms. | | Quotient Rule | ((\fracfg)' = \fracf'g - fg'g^2) | (\fracddx\fracx\ln x = \frac1\cdot\ln x - x\cdot(1/x)(\ln x)^2) | Ensure denominator never zero; simplify after differentiation. | | Chain Rule | (\fracddx f(g(x)) = f'(g(x))\cdot g'(x)) | (\fracddx,e^\sin x= e^\sin x\cos x) | Write inner and outer functions clearly; treat them as separate steps. | | | Constant Multiple | (\fracddx[c\cdot f(x)] =

Unlike standard textbooks that focus on formula application, Differential Calculus by Das and Mukherjee focuses on building the before the how . It is widely considered one of the best resources for strengthening the theoretical foundation of functions, limits, continuity, and differentiability. | | Quotient Rule | ((\fracfg)' = \fracf'g
