WebApr 24, 2024 · 广告. 之后,我们要知道,正弦函数sin和余弦函数cos,的对称轴不相同,所以对称中心也不同。. 比如说sinx和cosx之间是怎样转换的,最简单的就是用诱导公式:sin (π/2+α)=cosα cos (π/2+α)=—sinα。. 三角函数有很多公式,最常用的有“诱导公式”、“二倍角 … WebThe range of cscx is the same as that of secx, for the same reasons (except that now we are dealing with the multiplicative inverse of sine of x, not cosine of x).Therefore the range of cscx is cscx ‚ 1 or cscx • ¡1: The period of cscx is the same as that of sinx, which is 2….Since sinx is an odd function, cscx is also an odd function. Finally, at all of the points …
