How do you graph trigonometric functions?
You find the average rate of change of the function. That gives you the derivative on different points of the graph.
Why are first-degree functions called linear functions?
In the special case of two related variables (e.g., 2x - 7y + 5 = 0), the graph is a straight line.
What are the graphs of the inverse trigonometry functions?
If you reflect a function across the line y=x, you will have a graph of the inverse. For trigonometric problems: y = sin(x) has the inverse x=sin(y) or y = sin-1(x)
How is a percentage circle graph different from a degree circle graph?
Degree graph has 360 segments , percntage has 100 segments
Why do acoustics need trigonometry?
When people are taught trigenometry in school it is usually just for finding the angles of a triangle. But the sine and cosine functions are actually waves if you were to draw them on a graph. Acoustics is sound waves, and by mapping sound waves into trigonometric waves we can do calculations on them like addition.
