If an argument would result in an undefined value, the result isblank. This can happen, for example, when using inverse functions with arguments that are out of range. Syntax Primary Functions Cos(Radians) Cot(Radians) Sin(Radians) Tan(Radians) ...
sin_value = math.sin(angle_in_radians) 三、数学库和标准函数 这些函数一般位于语言的标准数学库中。这个库包含了一系列的数学相关函数不限于三角函数:sin、cos、tan,还有指数、对数等其他复杂函数,为解决数学问题提供了强大的工具。 四、实际应用和示例 ...
x=cos9t,y=sin9t,z=e0.9t,t≥0 Space Curves: Back in the days before most of us were born (which is to say as recently as the 1990's), sketching curves in three dimensions could be quite the chore. Fortunately, we live in the computer age, so ...
The fundamental period of the functions sin ɸ, cos ɸ, sec ɸ, and csc ɸ is the number 2π, which corresponds to an angle of 360°; the fundamental period of tan ɸ and cot ɸ is the number π, which represents an angle of 180°. The graphs of these trigonometric ...
