Math Problem Statement

limx->0 sinx =?

Solution

The limit of sin(x)\sin(x) as xx approaches 0 is given by:

limx0sin(x)=sin(0)=0\lim_{{x \to 0}} \sin(x) = \sin(0) = 0

This is because the sine function is continuous at x=0x = 0, and sin(0)\sin(0) equals 0.

Here are five related questions:

  1. What is the limit of cos(x)\cos(x) as xx approaches 0?
  2. How do you evaluate the limit limx0sin(x)x\lim_{{x \to 0}} \frac{\sin(x)}{x}?
  3. What is the derivative of sin(x)\sin(x) at x=0x = 0?
  4. How does the small-angle approximation sin(x)x\sin(x) \approx x for xx near 0 relate to limits?
  5. What is the Taylor series expansion of sin(x)\sin(x) around x=0x = 0?

Tip: For very small angles (in radians), sin(x)\sin(x) is approximately equal to xx, which is useful for simplifying expressions in calculus.
