The sine function, symbolized by sin(x), has zeroes at x = -π/2, -3π/2, -5π/2, and so on. These zeroes, also known as roots, occur where the sine function crosses the x-axis. Understanding the zeroes is crucial as they represent the points where the sine wave touches the x-axis, providing essential information about the graph's behavior.
The cosine function, denoted by cos(x), is periodic with a period of 2π. This means its graph repeats itself every 2π units along the x-axis. The periodicity of the cosine function is a fundamental concept in trigonometry, reflecting the repetitive nature of waves and cycles in physics and other sciences.
The range of the tangent function, tan(x), is all real numbers. This is because the tangent function can take on any value, both positive and negative, as x approaches π/2 or -π/2 from either side. Understanding the range of the tangent function is vital as it tells us the possible y-values that the function can attain.
The sine function has asymptotes at x = π/2 + kπ, where k is an integer. These asymptotes are vertical lines where the sine function approaches infinity or negative infinity. Knowing the asymptotes helps us understand the behavior of the sine function as it moves towards these lines.
The amplitude of the cosine function, cos(ax), is |a|. The amplitude represents the maximum distance of the graph from the x-axis. Understanding the amplitude is crucial as it allows us to analyze the "height" of the waves in the graph of the cosine function, providing a sense of the function's "size" or "strength".
