Method 1 – Using the MIN Function to Find the Minimum Value in Excel The syntax for the MIN function is MIN(number_range) number_range: The range from which you want to find the minimum value. Instead of the number_range, you can use multiple numbers separated by a comma (,), and...
y'=[-sinx(5+sinx)-cosx cosx]/(5+sinx)^2=-(5sinx+1)/(5+sinx)^2=0 ---> sinx=-1/5 所以有: 最大值当sinx=-1/5, cosx=2√6/5, ymax=2√6/(25-1)=√6/12=0.20 最小值当sinx=-1/5, cosx=-2√6/5, ymax=-2√6/(25-1)=-√6/12 =-0.20 反馈 收藏 ...
The minimum value of the function f(x) = (3 sin x - 4 cos x - 10) (3 sin x + 4 cos x - 10), is
三角函数最大值和最小值 Find the maximum and minimum values of the function.(Round your answers to two decimal places)y = 8x - 3sin 4x,x在0-2pi之间!急第一个,x=2kπ,k∈Z,时有最大值,最大值为1 1=2.x=kπ,k∈Z,时有最小值,最小值为-1 1=0.第二个,2x=π/2 2kπ,即x=π/...
The SMALL function returns the k-th smallest value from a group of numbers. The first argument is a cell range or array that you want to find the k-th smallest number in. The second and last argument is k which is a number from 1 up to the number of values you have in the first...

Find the minimum of the function f(w,x,y,z)=w^2+3wx+x^2+y^2+9yz+z^2, subject to conditions g(w,x)=w-x=100, and h(y,z)=y-z=200 ( ) A. (w,x,y,z)=(50,-75,100,-150) B. (w,x,y,z)=(50,-50,100,-100) C. (w,x,y,z)=(25,25,100,100) D...
FAQs on the min() Function in Python What Is the min() Function in Python and What Does It Do? In Python, the min() function returns the minimum value in an iterable or out of two or more given values. It can be used in two forms: with objects or with iterables. Unlike min()...
