一个角度可以用度（D）、分（M）和秒（S）来表示。1度 = 60分，1分 = 60秒。所以，如果我们有一个角度为 D度M分S秒，它可以用十进制度数表示为：Decimal_degree = D + (M/60) + (S/3600)计算器通常只接受十进制度数作为输入来计算正弦值。因此，我们需要将度分秒转换为十进制度数，然后再计算正弦...

The value of sin 21 degrees indecimalis 0.358367949. . .. Sin 21 degrees can also be expressed using the equivalent of the givenangle(21 degrees) in radians (0.36651 . . .). We know, usingdegree to radianconversion, θ in radians = θ in degrees × (pi/180°) ⇒ 21 degrees = 2...
设计Raptor算法,实现一个正弦函数计算器:输入任意一个角度值degree,计算并输出它的正弦函数值value。提示:使用Raptor中sin()函数进行计算,该函数的参数为弧度值;角度degree转弧度radian的计算公式为:radian=degree*pi/180;输入一个角度值后,需要转换为弧度值后再使用sin()函数进行计算。例如:输入30,则输出:“The sin...
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°) ⇒ 300 degrees = 300° × (π/180°) rad = 5π/3 or 5.2359 . . .∴ sin 300° = sin(5.2359) = -(√3/2) or -0.8660254. . ....
