arc的英文单词是arc，意思是在sincostancot之前找到这些三角函数对应的弧度值,反三角函数介绍:反三角函数包括:反正弦函数、反余弦函数、反余切函数、反余切函数，分别记为Arcsinx、Arccosx、Arctanx、Arccotx、Arcsecx、Arccscx。
1、数学里的arc是什么意思?在数学中，弧是反三角函数的符号。在解决某些问题时，某个角度的三角函数值并不特殊，比如tan=1/13。圆弧的作用就是表现这个非特殊的角度。刚才引用的角度大小可以表示为反正切1/13。arc的英文单词是arc，意思是在sincostancot之前找到这些三角函数对应的弧度值。角度值sin和arcsin是倒数函数cos，arccos是倒数函数tan，arctan是倒数函数cot，arccot是倒数函数。
2、arctanx的导数怎么求啊?arctanx的导数:y=arctanx，x=tany，dx/dy = secret =陈诗丹 1，dy/dx = 1/= 1/。如果函数x=fx=f在区间iyy和f0f0上单调可导，那么它的反函数y=f1y=f1在区间Ix={x|x=f，伊一} ix = {x | x = f，伊一}，and =1f或dydx=1dxdy=1f或dydx=1dxdy。
3、arctanx是什么意思arctanx=1/.Anx是正切函数，定义域是x|x2) k，kZ}，值域是r，Arctanx是反正切函数，定义域是r，反正切函数值域是2，2。推导过程:设x = tante，然后t=arctanx，两边取微分。dt/dx =成本.dt/dx=1/.因为x = tante所以上面的公式t=1/。反三角函数介绍:反三角函数包括:反正弦函数、反余弦函数、反余切函数、反余切函数，分别记为Arcsinx、Arccosx、Arctanx、Arccotx、Arcsecx、Arccscx。
4、为什么y= arcsecx这个函数会有不同的导函数?用绝对值写的东西是严格的。有两种方法可以解释为什么包含绝对值:= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = x^=cosy；从两边推导得到:-x = y *；Y=1/，siny = 2)= =/| x |；y = 1/= 1/= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = y =arcsecx，x = secy；x = secy * tgy = x * tgy；y = 1/x = 1/；1)当-。
