Evaluate the Limit limit as x approaches 0 of sin(pi/x)
Problem
Solution
Analyze the behavior of the inner function
π/x asx approaches0 Asx gets closer to0 from the right,π/x approaches∞ and asx gets closer to0 from the left,π/x approaches−∞ Observe the behavior of the sine function. The function
sin(θ) oscillates infinitely many times between−1 and1 asθ approaches∞ or−∞ Determine the limit behavior. Since the value of
sin(π/x) continues to oscillate between−1 and1 and does not settle on a single value asx approaches0 the limit does not exist.
