Note 3:
We say that because both left hand limit and right hand limit are finite and equal. If there exists a real number l such that if |f (x) - l| can be made as small as we possible by taking x sufficiently close to a, then l is called the limit of f (x) as x tends to 'a'...

Limits of polynomial functions can be found by substitution If f(x) = a n x n + a n - 1 x n - 1 +a n - 2 x n - 2 +.. a 0 , the..

We know that 64 = 2 x 2 x 2 x 2 x 2 x 2 = 2 6 We know that 64 = 2 x 2 x 2 x 2 x 2 x 2 = 2 6 Here 2 is called the base and 6 is called the power (or index or exponent). We say that "64 is equal to base 2 raised to the power 6". Similarly, if m is a positive integer and then a a a m times = a ..
Summary
1) a m a n = a m+n 2) a m /a n = a m-n 3) (a m ) n = a mn..

In case of inequation < or >, draw the line dotted otherwise draw the line thick. This line divides the plane into two equal part..

Linear inequations denote a user-friendly branch of mathematics which enables us to be very comfortable with the number line and properties of numbers.Linear inequations denote a user-friendly branch of mathematics which enables us to be very comfortable with the number line and properties of numbe..
Graphs of linear inequations
Consider the equation x = 0, x = 1, y = 0, y = -2. i) x = 0 represents y-axis. ii) x = 1 represents line parallel to y-axis. iii) y = 0 represents x-axis. iv) y = -2 represents line parallel to x-axis...

Graph the following: x > 2 and y < 3 The solution set of the system of linear simultaneous inequations is the set of all points (x, y) which satisfies the given set of inequations. In the above graph, the common area of the inequations (shaded area) represents solution set. y < 3 is th..

For every concept, here we get explanation along diagrams, I really liked it very much
I had Algebra assignment to be finished when I came across this site. I good great help finishing my assignment once I joined their service. Thanks !
I asked a Math question in the chat box in tutorvista. I was amazed to see live response from the tutor who helped me with my questions. That was great. I joined their online regular tutoring so that I can get such help anytime. - Mary
