Degree angles角的测量(度数) A way to measure angles is in terms of degrees, denoted by the symbol°. A measure of one degree (1°) is equivalent to a rotation of a complete revolution about the vertex. 角的大小可以用度数测量,...

为避免被缓存而需要产生一个独一无二的数字追加在URL尾端,通常最佳方法是取得当前毫秒数. 【弧度(radian)与度数(degree)之间的转换】 从弧度转为度数: degrees = radians * 180 / Math.PI 从度数转为弧度: radians = degrees * Math.PI / 180 【计算两点之间的距离】 勾股定理: c2 = a2 + b2 假设有两...
在最近的时代,弧度(radian)或圆度量(circular measure)已被普遍采用为角度度量的自然单位。1弧度是指这样的一个大小的角:以圆心为顶点向圆周辐射,其正对向的沿圆周环绕(circumference)一个半径长度的圆弧所对应的角(见下图5)。因为沿着圆周绕一个完整的圈是2π个半径(radii,单数radius)(2π≈2.68, π表示圆周率...
This amplitude instantaneous amplitude is multiplied by the 180/pi which is an offset coefficient (as you say one radian converted to degrees) because the time axis is in degrees in this version of the equation. positive amplitudes (angles between zero and 180 degress result in time advancing ...
