About Me

Hello guys! I am Mohan Singh 

Welcome to Mathematical World, your number one source for all things related to Mathematics. I am dedicated to giving you the very best of Mathematics Solutions with a focus on quality and real-world problem solution.

Founded in 2021-03-25 by Mohan Singh, Mathematical World has come a long way from its beginnings in 226202 located in India. When I first started out, my passion for Mathematics drove us to start my own blog/website.

We hope you enjoy my blog as much as I enjoy offering them to you. If you have any questions or comments, please don't hesitate to contact me.

Sincerely, Mohan Singh

Indefinite Integration - Notes, Concept and All Important Formula

INDEFINITE INTEGRATION If  f & F are function of \(x\) such that \(F^{\prime}(x)\) \(=f(x)\) then the function \(F\) is called a PRIMITIVE OR ANTIDERIVATIVE OR INTEGRAL of \(\mathrm{f}(\mathrm{x})\) w.r.t. \(\mathrm{x}\) and is written symbolically as \(\displaystyle \int \mathrm{f}(\mathrm{x}) \mathrm{d} \mathrm{x}\) \(=\mathrm{F}(\mathrm{x})+\mathrm{c} \Leftrightarrow \dfrac{\mathrm{d}}{\mathrm{dx}}\{\mathrm{F}(\mathrm{x})+\mathrm{c}\}\) \(=\mathrm{f}(\mathrm{x})\) , where \(\mathrm{c}\) is called the constant of integration. Note : If \(\displaystyle \int f(x) d x\) \(=F(x)+c\) , then \(\displaystyle \int f(a x+b) d x\) \(=\dfrac{F(a x+b)}{a}+c, a \neq 0\) All Chapter Notes, Concept and Important Formula 1. STANDARD RESULTS : (i) \( \displaystyle \int(a x+b)^{n} d x\) \(=\dfrac{(a x+b)^{n+1}}{a(n+1)}+c ; n \neq-1\) (ii) \(\displaystyle \int \dfrac{d x}{a x+b}\) \(=\dfrac{1}{a} \ln|a x+b|+c\) (iii) \(\displaystyle \int e^{\mathrm{ax}+b} \mathrm{dx}\) \(=\dfrac{1}{...

Circle- Notes, Concept and All Important Formula

CIRCLE 1. DEFINITION : A circle is the locus of a point which moves in a plane in such a way that its distance from a fixed point remains constant. The fixed point is called the centre of the circle and the constant distance is called the radius of the circle. All Chapter Notes, Concept and Important Formula 2. STANDARD EQUATIONS OF THE CIRCLE : (a) Central Form: If \((\mathrm{h}, \mathrm{k})\) is the centre and \(\mathrm{r}\) is the radius of the circle then its equation is \((\mathbf{x}-\mathbf{h})^{2}+(\mathbf{y}-\mathbf{k})^{2}=\mathbf{r}^{2}\) (b) General equation of circle : \(\mathbf{x}^{2}+\mathbf{y}^{2}+\mathbf{2 g x}+\mathbf{2 f y}+\mathbf{c}=\mathbf{0}\) , where \(g, \mathrm{f}, c\) are constants and centre is \((-g,-f)\) i.e. \(\left(-\frac{\text { coefficient of } \mathrm{x}}{2},-\frac{\text { coefficient of } \mathrm{y}}{2}\right)\) and radius \(r=\sqrt{g^{2}+f^{2}-c}\) Note : The general quadratic equation in \(\mathrm{x}\) and \(\mathrm{y}\) , \(a x^{2}+b y^{2}+2 ...

Continuity - Notes, Concept and All Important Formula

CONTINUITY 1. CONTINUOUS FUNCTIONS: A function \(f(x)\) is said to be continuous at \(x=a\) , if \(\displaystyle \lim _{x \rightarrow a} f(x)\) exists and is equal to \(f(\) a). Symbolically \(f(x)\) is continuous at \(x=a\) . If \(\displaystyle \lim _{h \rightarrow 0} f(a-h)=\displaystyle \lim _{h \rightarrow 0} f(a+h)=f(a)=\) finite and fixed quantity \((\mathrm{h}>0)\) . i.e. \(\left.\mathrm{LHL}\right|_{\mathrm{x}=\mathrm{a}}=\left.\mathrm{RHL}\right|_{\mathrm{x}=\mathrm{a}}=\) value of \(\left.f(\mathrm{x})\right|_{\mathrm{x}=\mathrm{a}}=\) finite and fixed quantity. At isolated points functions are considered to be continuous. All Chapter Notes, Concept and Important Formula 2. CONTINUITY OF THE FUNCTION IN AN INTERVAL: (a) A function is said to be continuous in \((a, b)\) if \(f\) is continuous at each & every point belonging to \((a, b)\) . (b) A function is said to be continuous in a closed interval \([a, b]\) if :   \(\circ\,\, \mathrm{f}\) is continu...
