Some of the important formuals that students must go through have been shared below:
Limits
- limx→0sinxx=1\lim_{x \to 0} \frac{\sin x}{x} = 1limx→0xsinx=1
- limx→01−cosxx2=12\lim_{x \to 0} \frac{1 - \cos x}{x^2} = \frac{1}{2}limx→0x21−cosx=21
Differentiation
- ddx(xn)=nxn−1\frac{d}{dx}(x^n) = nx^{n-1}dxd(xn)=nxn−1
- ddx(sinx)=cosx\frac{d}{dx}(\sin x) = \cos xdxd(sinx)=cosx
- ddx(ex)=ex\frac{d}{dx}(e^x) = e^xdxd(ex)=e
Integration
- ∫xndx=xn+1n+1+C\int x^n dx = \frac{x^{n+1}}{n+1} + C∫xndx=n+1xn+1+C
- ∫1xdx=ln∣x∣+C\int \frac{1}{x} dx = \ln|x| + C∫x1dx=ln∣x∣+C
Binomial Theorem
- (a+b)n=∑r=0n(nr)an−rbr(a+b)^n = \sum_{r=0}^{n} \binom{n}{r} a^{n-r} b^r(a+b)n=∑r=0n(rn)an−rbr
Distance Formula (3D)
- d=(x2−x1)2+(y2−y1)2+(z2−z1)2d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2 + (z_2-z_1)^2}d=(x2−x1)2+(y2−y1)2+(z2−z1)2
