TAN instruction has two parameters, one is radian value and the other is result. For example, TAN D0 is D2, and D2 is the tangent of D0.

It should be noted that trigonometric functions are all in radians, so to calculate the trigonometric function of an angle, it is necessary to use RAD instruction to convert the angle into radians and perform trigonometric function operation.

Hope to adopt. . . . . .
