This is the mathematics formulae book for class 12 students. Here, we have covered all the formulae needed to solve the questions of Mathematics. Permutation The total arrangement of total objects taken some or all at a time is called permutation. The permutation of 'n' objects taken 'r' at a time is denoted by $^np_{r}$ and is defined by; 1. $^np_{r}=\frac{n!}{(n-r)!}$ 2. Permutation of an object, all different;$$=\frac{n!}{p!\,q!\,r!}$$ where,  n=total objects p=repetition of first kind  q=repetition of second kind r=repetition of third kind 3. Circular permutation= $(n-1)!$ 4. If clockwise and anticlockwise arrangement are not distinguishable [necklace of beads and beads into bracelet]; Total number of permutation=$\frac{(n-1)!}{2}$ Combination The selection of total objects taken some or all at a time is called combination. The combination of 'n objects taken 'r' at a time is denoted by $^nc_{r} \, or \, c(n,r)$ and defined by; $$^nc_{r}=\frac{n!}{(n-r)!...

Disinformation is when false or misleading information is spread on purpose to trick or confuse people. It is like someone telling a lie or making up stories to make others believe something that isn't true. Disinformation can be found in many places, like social media, news articles, or even on online videos. Sometimes, people create disinformation to make others think a certain way or to cause trouble to others.  It's important to be careful and not believe everything we see or hear. We should always try to verify information from reliable sources before accepting it as true. A critical thinker will always ask the questions in different way to verify whether the information is true or false. The questioning technique used by them are, they ask why, what, who, where, when, and how. They inquiry the information from different perspectives. In the recent days, with the advancement in information, the case of disinformation is increasing rapidly. Let's see an example where Sa...

I have felt the difference between my school and Access class. We don't do anything interesting in school except reading and maintaining discipline. But in Access class, we do many activities such as working in a team or pair, play English language games, develop leadership, observe, and learn various cultures of Nepal and America. Not only that it has helped us in participating in different kinds of activities as well as community service programs such as animal feeding, cleaning campaign and others. Not only in education, there are differences between school teachers and Access teachers as well. School teachers are very strict but Access teachers are very kind, friendly, helpful, and responsible. They also encourage and motivate all Access students. They never punish but rather they give us some positive suggestions and encourage us to be positive towards others. They love and care for us like parents. I have more friends in Access than in my school. They are very friendly and ac...
