We can use the geometric interpretation to design functions and startingThe period of the sine function is 2π. This means that the value of the function is the same every 2π units. Similar to other trigonometric functions, the sine function is a periodic function, which means that it repeats at regular intervals. The interval of the sine function is 2π. For example, we have sin(π) …Goodness, no! That's silly. In fact, it's a sin. (Sorry!) To find the inverse of an equation such as sin x = 1/2, solve for the following statement: "x is equal to the angle whose sine is 1/2."In trig speak, you write this statement as x = sin - 1 (1/2). The notation involves putting a -1 in the superscript position.10.6 Functions with period 2L If afunction has period other than 2π, we can find its Fourierseries by making a change of variable.

Hence incase of cos (4x) it’ll be 360/4=90 hence the cycle will complete in 90° or 1/2 6.5K views Promoted by The Penny Hoarder Should you leave more than $1,000 in a checking account?
