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.

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

Frances Ellen Watkins Harper Very soon the Yankee teachers Came down and set up school; But, oh! how the Rebs did hate it,— It was agin' their rule. Our masters always tried to hide Book learning from our eyes; Knowledge didn't agree with slavery— 'Twould make us all too wise. But some of us would try to steal A little from the book, And put the words together, And learn by hook or crook. I remember Uncle Caldwell, Who took pot-liquor fat And greased the pages of his book, And hid it in his hat. And had his master ever seen The leaves up on his head, He'd have thought them greasy papers, But nothing to be read. And there was Mr. Turner's Ben, Who heard the children spell, And picked the words right up by heart, And learned to read 'em well. Well, the Northern folks kept sending The Yankee teachers down; And they stood right up and helped us, Though Rebs did sneer and frown. And, I longed to read my Bible, ...
