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.
Note that in the notation (commonly used in North America and in pocket calculators worldwide), denotes the tangent and the inverse function, not the multiplicative inverse. The principal value of the inverse tangent is implemented as ArcTan[z] in the Wolfram Language. In the GNU C library, it is implemented as atan(double x). The inverse tangent is a multivalued function and hence requires a branch cut in the complex plane, which the Wolfram Language's convention places at and . This follows from the definition of as (1)
