To find the minimum and maximum values of sin(x) + cos(x), we can start by considering the extreme points of each individual function. The minimum value of sin(x) is -1, which occurs when x is equal to -π/2 + 2πn, where n is an integer. Similarly, the minimum value of cos...
In conclusion, the integral of sin(x) e^cos(x) is equal to the integral of cos(x) e^cos(x). 中文回答: 要计算sin(x)乘以e的cos(x)次方的积分,我们可以使用分部积分法。假设u = sin(x),dv = e^cos(x) dx。我们可以分别求出du和v,分别对应微分和积分。 du = cos(x) dx. v = ∫e...
