Math Problem Statement

Draw the graph of sin 1/x and explain the steps

Solution

Here's the graph of f(x)=sin(1x)f(x) = \sin\left(\frac{1}{x}\right). As expected, the function oscillates rapidly between -1 and 1 as xx approaches 0 from both sides, and the oscillations become more gradual as x|x| increases. The graph doesn't include x=0x = 0 because the function is undefined there.

Key Observations:

  • For xx close to 0, the graph oscillates infinitely, which is why it appears densely packed near the origin.
  • For larger values of xx, the oscillations smooth out and resemble a standard sine curve but with decreasing frequency.

Would you like more details or have any questions? Here are some related questions to consider:

  1. What happens if we try to evaluate the limit of sin(1x)\sin\left(\frac{1}{x}\right) as xx approaches 0?
  2. How does the behavior of f(x)=sin(1x)f(x) = \sin\left(\frac{1}{x}\right) change when you introduce a shift or scaling factor?
  3. Can you describe why the function is not continuous at x=0x = 0?
  4. What other functions behave similarly near x=0x = 0?
  5. How would the graph change if we used cos(1x)\cos\left(\frac{1}{x}\right) instead of sin(1x)\sin\left(\frac{1}{x}\right)?

Tip: Functions with oscillations near a point, like sin(1x)\sin\left(\frac{1}{x}\right), often have undefined limits at that point due to the rapid change in values.
