Now, the formula for this rule considers the rates of change of each factor in expressing the derivative of the function. Answer and Explanation: Given data: We are given the function, y=xcos−1(x) Our objective is to find the derivative of the function, y'. We......
[ \cos(\theta) = \frac{x}{r} ] 其中,r 是从原点到点 (x, y) 的距离(即半径),而 x 是该点在 x 轴上的坐标。在一个单位圆上(半径为1的圆),这个定义可以简化为: [ \cos(\theta) = x ] 性质 周期性:余弦函数是一个周期函数,周期为2π。这意味着对于任何实数k和角度θ,都有: [ \cos(...
