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)!...

 “If you’ve ever been around someone with a no-limitation mentality, you are sure to remember them,” says Paul J. Meyer, author of “Pink Slip Proof: How to Control All Future Paychecks.” “They don’t know the word ‘can’t.’ It’s not in their vocabulary. They simply expect things to work out in the best way possible.” Meyer emphasizes that adopting a no-limitation mentality can help you succeed in life and work. You attract what you think about. Negative thoughts bring hardships, while positive thoughts open doors. “Positive thoughts are the basis for success attitudes and success habits, both leading to positive expectancy in everything we do,” says Meyer. How can you adopt positive expectancy and a no-limitations mindset? Meyer suggests the following: – Wake up every day trying to find solutions. Always assume the problems can be solved, then figure out how to get the job done. – Concentrate on your strengths. Capitalize on what you can do, rather than your weaknesses. For exam...

Technology is the use of scientific knowledge to produce new machinery and devices that can be used to provide different services or can be employed further to create more devices. The application of information to design and produce machines and other goods to make life more convenient for the human beings is known as technology. Here are some essays of varying lengths on Technology to help you with the topic in your class tests and exams. Scientists conduct research and experiment with different things to come up with newer ideas. Technologists use these ideas to develop newer devices. People these days have grown extremely accustomed to the use of these technological inventions that they simply cannot do without them. They await the launch of newer and more advanced devices. Mobile phones and cars are the best examples of this. People wait for the new models and replace them without giving it a second thought. The smart phones offer so much, from amazing gaming experience to instant...
