Explanation Definition used: Greatest integer function: 〚 x 〛 = the largest integer that is less than or equal to x . Theorem 1: The limit lim x → a f ( x ) = L if and only if lim x → a − f ( x ) = L = lim x → a + f ( x ) . Proof: Construct a table of y = 〚 x 〛 for some arbitrary values of x. x −3 −2.5 −2 −1.9 −1 −0.7 0 0.7 1 1.9 2 2.5 3 y −3 −3 −2 −2 −1 −1 0 0 1 1 2 2 3 Draw the graph of y = 〚 x 〛 using the table as shown in Figure 1. Construct a table of y = 〚 − x 〛 for some arbitrary values of x. x −3 −2.5 −2 −1.9 −1 −0.7 0 0.7 1 1.9 2 2.5 3 y 3 2 2 1 1 0 0 −1 −1 −2 −2 −3 −3 Draw the graph of y = 〚 − x 〛 using the table as shown in Figure 2. Obtain the limit of the function f ( x ) = 〚 x 〛 + 〚 − x 〛 as x approaches 2. lim x → 2 f ( x ) = lim x → 2 ( 〚 x 〛 + 〚 − x 〛 ) Obtain the limit of the function f ( x ) = 〚 x 〛 + 〚 − x 〛 as x approaches left-hand side of 2. lim x → 2 − f ( x ) = lim x → 2 − ( 〚 x 〛 + 〚 − x 〛 ) = lim x → 2 − 〚 x 〛 + lim x → 2 − 〚 − x 〛 [ by limit law 1 ] From the Figure 1 and 2, it is observed that lim x → 2 − 〚 x 〛 = 1 and lim x → 2 − 〚 − x 〛 = − 2 . lim x → 2 − 〚 x 〛 + lim x → 2 − 〚 − x 〛 = 1 + ( − 2 ) = 1 − 2 = − 1 Obtain the limit of the function f ( x ) = 〚 x 〛 + 〚 − x 〛 as x approaches right-hand side of 2. lim x → 2 + f ( x ) = lim x → 2 + ( 〚 x 〛 + 〚 − x 〛 ) = lim x → 2 + 〚 x 〛 + lim x → 2 + 〚 − x 〛 [ by limit law 1 ] From the Figure 1 and 2, it is observed that lim x → 2 + 〚 x 〛 = 2 and lim x → 2 + 〚 − x 〛 = − 3 . lim x → 2 + 〚 x 〛 + lim x → 2 + 〚 − x 〛 = 2 + ( − 3 ) = 2 − 3 = − 1 Therefore, the left and right side limits are equal

Rate of Change

The relation between two quantities which displays how much greater one quantity is than another is called ratio.

Slope

The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
