About
Simple and Easy Learning
Tutorials Point originated from the idea that there exists a class of readers who respond better to online content and prefer to learn new skills at their own pace from the comforts of their drawing rooms.
The journey commenced with a single tutorial on HTML in 2006 and elated by the response it generated, we worked our way to adding fresh tutorials to our repository which now proudly flaunts a wealth of tutorials and allied articles on topics ranging from programming languages to web designing to academics and much more.
40 million readers read 100 million pages every month
Our Text Library Content and resources are freely available and we prefer to keep it that way to encourage our readers acquire as many skills as they would like to. We don't force our readers to sign up with us or submit their details either to use our Free Text Tutorials Library. No preconditions and no impediments, Just Simply Easy Learning!
We have established a Digital Content Marketplace to sell Video Courses and eBooks at a very nominal cost. You will have to register with us to avail these premium services.

Rotational symmetry:- When an object is rotated about the center by a number of degrees and the object appears to be the same. It is known as the rotational symmetry of the object.The order of symmetry is the number of positions the object looks the same in a $360^{\circ}$ rotation.The ... Read More

When a figure is folded in half, along its line of symmetry, both the halves match each other exactly. This line of symmetry is called the axis of symmetry. $(a)$. An equilateral triangle has three lines of symmetry.$(b)$. An isosceles triangle has one line of symmetry.$(c)$. A scalene triangle has no line of symmetry.$(d)$. A square has four lines ...

To do:We have to verify whether the given values are zeroes of the given polynomials. Solution:The zero of the polynomial is defined as any real value of $x$, for which the value of the polynomial becomes zero.Therefore, (i) \( p(x)=3 x+1, x=-\frac{1}{3} \)$p(-\frac{1}{3})=3(-\frac{1}{3})+1$$=-1+1$$=0$Therefore, $x=-\frac{1}{3}$ is the zero of the polynomial $p(x)=3 ...
