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.
The period of the function is 360Â° or 2Ï radians. You can rotate the point as many times as you like. This means you can find the tangent of any angle, no matter how large, with one exception. If you look at the graph above you see that tan90Â° is undefined, because it requires dividing by zero. Therefore, angles like this are not in the domain of the tan functions and produce an undefined result. Try tan90Â° on your calculator and you will get an error, whereas say 89.99 will work.
