What do the functions cosx/x and tanx/x represent?
Cosx/x and tanx/x represent the trigonometric functions cosine and tangent, respectively, divided by the variable x.
The graph of cosx/x and tanx/x is a continuous, non-linear curve. The graph of cosx/x has a horizontal asymptote at y=1, while the graph of tanx/x has vertical asymptotes at x=0 and x=±π.
The properties of cosx/x and tanx/x include being periodic, having a range of all real numbers, and being odd functions (symmetric about the origin). Additionally, the absolute value of cosx/x is always less than or equal to 1, while the absolute value of tanx/x is always greater than or equal to 1.
Cosx/x and tanx/x are used in various fields such as engineering, physics, and astronomy to model real-world periodic phenomena, such as sound waves and planetary orbits. They are also used in navigation and surveying to calculate distances and angles.
The limit of cosx/x as x approaches 0 is 1, and the limit of tanx/x as x approaches 0 is 1. This means that as x gets closer and closer to 0, the value of cosx/x and tanx/x approaches 1.
