Essential Formulas to Review
Memorizing and understanding fundamental formulas is critical. Key formulas from Limits, Differentiation, Integration, Binomial Theorem, and 3D Geometry are provided below.
Limits Formulas
- \(\lim_{x \to 0} \frac{\sin x}{x} = 1\)
- \(\lim_{x \to 0} \frac{1 – \cos x}{x^2} = \frac{1}{2}\)
Differentiation Formulas
- \(\frac{d}{dx}(x^n) = nx^{n-1}\)
- \(\frac{d}{dx}(\sin x) = \cos x\)
- \(\frac{d}{dx}(e^x) = e^x\)
Integration Formulas
- \(\int x^n dx = \frac{x^{n+1}}{n+1} + C\)
- \(\int \frac{1}{x} dx = \ln|x| + C\)
Binomial Theorem Formula
- \((a+b)^n = \sum_{r=0}^{n} \binom{n}{r} a^{n-r} b^r\)
Distance Formula (3D)
- \(d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2 + (z_2-z_1)^2}\)
