    Standing Waves (tension vs. wavelength)

    Homework Statement I'm trying to decode a graph of Tension vs. \lambda^2 of standing waves on a string to understand the actual meaning of the slope. I also need to derive the equation for the line from two expressions: v= \sqrt{T/\mu} v= f\lambda Homework Equations...

    Indeterminant limit (radical in denominator)

    Homework Statement \lim_{x \to {4}}\frac{4 - x^2}{2 - \sqrt{x}} Homework Equations The Attempt at a Solution \lim_{x \to {4}}\frac{4 - x^2}{2 - \sqrt{x}} \cdot \frac{2 + \sqrt{x}}{2 + \sqrt{x}} = \frac{x(4-x)(2-\sqrt{x})}{(4-x)} = x(2-\sqrt{x}) this equals zero, but is the limit...
