已知函数y=2cos(x+π/4)(-π/4≤x≤7π/4)的图像与直线y=2所围成的平面
2-2cos(x+π/4)在)-π/4到7π/4上积分么具体你自己会算吧
高一数学三角函数图像题一道,如将题目中的sin改为cos后该如何计算?
做选择题,始终是找函数值取得最值的时候对应的x值。sin,保证括号内来自等于π/2时cos,保证为0。然后根据图像可以知道,最值点前后半个周期即为单调增减区间。再考虑周期。

你那个是对数组求差了,y2数组的值是y1数组相邻两个的差值急,就是y2(n)=y1(n+1)-y1(n)n=1:length(y1)-1,所以向量维数少一个试试这个,两种方法,一...
