These trigonometric functions refer to the sine and cosine of an angle, that is: The ratio between the adjacent leg and the hypotenuse, in the case of cosine. And the ratio between the opposite leg and the hypotenuse, in the case of sine. Its syntax is as follows: We can use both “...
除了正弦函数外,还有余弦函数(cosine function)和正切函数(tangent function)。 正弦函数用于表示三角形中角度与对边的比,而余弦函数用于表示角度与邻边的比,正切函数则表示角度与对边和邻边的比。正切函数中的A可以大于360°,但需注意有些角度没有正切值,如90°。总之,正弦和余弦函数适用于各种角度的三角形,不仅限...

A cosine function is graphed starting at (0,1). Mark the x-axis 90, 180, 270, and 360 for degrees or their values in radians (pi/2, pi, 3pi/2, 2pi). Since sine relates the ratio of x to the radius of the triangle formed on the unit circle, at 90 (pi/2) the value of ...
