A formula is formed by using: (a) mathematical symbols and variables (b) given conditions, and (c) simplificatio..
Framing of Formulae
We use alphabets like x, y, z etc., to denote variables. For example the length of a rectangle is denoted by 'l'. It takes different values in different rectangles. A formula is a relation between different variables formed using mathematical symbols. Any given condition can be translat..
Summary
In a given sentence, the variables are replaced by letters and the different operations are replaced by their mathematical symbols. We now arrive at a formula. In a given sentence, the variables are replaced by letters and the different operations are replaced by their mathematical ..
Left Hand Limit
Let f(x) tend to a limit l 1 as x tends to a through values less than 'a', then l 1 is called the left hand limit which is symbolically written ..

A statement is an assertion or a sentence that is either true or false, but not both. A variable is a symbol that may represent any member of a specified set called replacement set or domain of that variable. A mathematical expression is a symbolic repr..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
Tutor Vista tutors actually helped me to think through some of the problems instead of just doing them for me.Now i am more confident with math ,Thank you all
Tutor Vista tutors are extremely helpful, patient, and nice to me. They are very talented and experienced tutors! Keep up the good work! - Loren
