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)!...

Father KN Waiba and mother Amrit Moktan gave a birth to a new child in Ligiya Tea Garden, Darjeeling, India in the year of BS 1994, Baishakh and they baptised the newly born child Bishnu Kumari Waiba. The child later chose ‘Parijat’ as her pen name when she ventured into the world of literature. She suffered from the diseases like tuberculosis, asthma, and rheumatism, a bright star of Nepali literature couldn’t continue her higher education after she completed graduation from Padma Kanya Campus, Kathmandu. Her first poem was published in the ‘Dharti’ magazine in 2013 BS. She is a poet, essayist, storyteller and novelist too. Her writing depicted the feelings of underprivileged and marginalised people. She is famous for her novels Siris Ko Phool, Mahattahin, Bainsh Ko Manche, Parkhal Bhitra Ra Bahir, Toribari Bata Ra Sapanaharu, and Antermukhi. Image source: Wikipedia
