Cash and savings accounts are the most common type of liquid asset owned by people and businesses alike, but other assets considered to be liquid, are those that are established on the market and can be transferred between owners easily. Examples of liquid assets include: Certifications of deposit.
The tangent will be undefined wherever its denominator (the cosine) is zero. Thinking back to when you learned about graphing rational functions, a zero in the denominator means you'll have a vertical asymptote. So the tangent will have vertical asymptotes wherever the cosine is zero: at âÏ/2, Ï/2, and 3Ï/2.
Best Answer: The problem here is not that the limit is undefined, but rather that teh function is multivalued at x = 0. There is a discontinuity at x = 0. There is no asymptote. x/|x| consists of two disconnected lines. That's why the limit at x = 0 does not exist. Just to test it out, work out x/|x| for x = -0.001 and x = +0.001. See what you get. Just as a side note, if you obtained the Fourier series for x/|x|, it would return the value 0 at x = 0.
