- EXAMPLE 3 Evaluate the limit below and indicate which properties of limits are used at each stage. lim x → ∞ 5x2 − 5x − 2/ 4x2 + 3x + 1 SOLUTION As x becomes large, both numerator and denominator become large, so it isn't obvious what happens to their ratio. We need to do some preliminary algebra.To evaluate the limit at infinity of any rational function, we first divide both numerator and denominator by the highest power of x that occurs in the denominator. (We may assume that x ≠ 0, since we are interested only in large values of x.) In this case the highest power of x in the denominator is x2, so we have lim x → ∞ 5x2 − 5x − 2/ 4x2 + 3x + 1 = lim x → ∞ 5x2 − 5x − 2/x2 4x2 + 3x + 1/x2 = lim x → ∞ 5 − 5/x − 2/x2 4 + 3/x + 1/x2 = lim x → ∞ 5 − 5/x − 2/x2 lim x → ∞ 4 + 3/x + 1/x2…The graph of the function f(x)=cotxf(x)=cotx is given above for the interval x∈[0,2π]x∈[0,2π] ONLY.Determine the one-sided limit.
