y = sinx. The values of y are found from a table of trigonometric functions.In plotting it is desirable to express x in circular measure; for example,for the angle 180° we lay offx = it = :$.141l). When x is amultiple of it, y — 0 ; when x is an odd multiple of -, y = ± 1; for other values of x, y…
