Trigonometric functions have distinct cycles, or "phases"; think of first period of the basic sine wave. A phase shift means nothing more than shifting a given trig function to the left or right, so that the cycle starts at a non-regular point; in other words, that the graph has been ...
Sketch both cubic functions on the same set of coordinate axes. An Experiment to Study "Reflection Across the Y-axis" Sketch and compare: y=(x−4)3y=(x−4)3 VS. y=(−x−4)3y=(−x−4)3 Compared to the graph of y=(x−4)3y=(x−4)3: • the graph of y=(...

You can see this graphically if you graph the two cofunctions, sine and cosine, on the same graph. They look like the same function, just shifted along the x axis. Unpacking Complementary Angles Complementary angles are angle pairs whose sum adds up to a right angle: 90°, or π/2radian...
How do you graph a hyperbola?Question:How do you graph a hyperbola?Asymptotes:Asymptotes are invisible lines that the curve of a function gets infinitely close to but never touches. You see asymptotes when graphing parabolas, trig functions and complex rational functions.Answer...
In trigonometry, the period of a function refers to the distance of a function's wave. Learn how to find the period of a trig function by exploring...
To find the inverse of a trigonometric function, it pays to know about all the trig functions and their inverses. For example, if you want to find the inverse of y = sin(x), you need to know that the inverse of the sine function is the arcsine function; no simple al...
In this lesson, find a trig functions chart and learn about graphing trig functions. See various trig graphs, including sinusoidal functions and their graphs. Related to this QuestionHow do you graph y = sin(2x) - 2? What is the graph of y = sin^2(x)? Graph f(x) = sin(x). What...
What is the formula to find amplitude? Amplitude is half of the difference between the max and min values of a periodic function. Therefore, amplitude = (max - min)/2. How do you find the amplitude of a trig graph? To find the amplitude of a trig graph, first, determine the max and...
When expressed on a graph, some functions are continuous from negative infinity to positive infinity. However, this is not always the case: other functions break off at a point of discontinuity, or turn off and never make it past a certain point on the graph. Vertical and horizontal asymptote...
