Volume = sin xdx=(π/2)∫[1-cos(2x)]dx
π/2)[x-sin(2x)/2]│
Any continuous line is called a curve. Including straight lines, polylines, line segments, arcs, etc. The curve that turns everywhere generally has an infinite length and an area of zero, and in this case, the curve itself is a space greater than 1 and less than 2 dimensions.
Graphical properties of y=sinx:
1. Define the domain, the set of real numbers r
2. Value range, [-1,1].
3. Maximum value and zero point.
Maximum: when x=2k+(2), kz, y(max)=1 min: when x=2k+(3 2), kz, y(min)=-14, zero point: (k,0), kz
5. Symmetry.
Axis of symmetry: about the line x=(2)+k,kz symmetry central symmetry: about the point (k,0),kz symmetry6, periodicity, minimum positive period: 2

<> is just a reference to accompany Bu Min stupidly.

The coordinates of the intersection of the image and the y-axis are (0,m).The coordinates of the intersection point with the x-axis are (m 2,0), so the area of the triangle is: m m 2 (1 2)=1 solution m=2 or -2

From a(3,0), we can know that when x 3, y 0, gets.
3²+6+m=0
m3 m value is 3

The combination of numbers and shapes, the bottom is m 2, the height is m, and the solution m is plus or minus 2.

Summary. The x-axis and y-axis are the lines that define the drawing area of the chart and are used as a frame of reference for measurements. The x-axis is usually horizontal and contains classification, and the y-axis is usually vertical and contains data.
As long as you make a chart first, right-click on the data series (that is, curves or squares in the chart), select the data series format, select the axis label in the pop-up window, and then select "The data series is drawn on the secondary axis", OK, and adjust the format yourself.
by y=|1-x^2|Rotate the volume around the x-axis with x=0, x=2 and x-axis enclosed by a figure.
You can take a picture of ** and send it over.
Can you hurry up, I'll have class in a moment.
Hello, dear, sorry, I've been waiting for a long time, by y=|1-x^2|Rotate the volume around the x-axis with x=0, x=2 and x-axis in a figure: the volume formula of the rotating body: v=( The surface formed by a plane curve rotating in a straight line around a trace in the plane where it is located is called a rotating surface; This fixed line is called the axis of the rotating body; The geometry enclosed by a rotating surface is called a rotating body.
The x-axis and y-axis are the lines that define the drawing area of the chart and are used as a frame of reference for measurements. The x-axis is usually horizontal and contains classification, and the y-axis is usually vertical and contains data. As long as you make a base Huai chart, right-click on the data series (that is, the curves or squares in the chart), select the format of the data series, select the axis label in the pop-up window, and then select "The data series is drawn on the secondary axis", OK, and adjust the format yourself.
I want to know what the volume is.
The formula for calculating the volume of the rotating body is v=pi 2 d x to get v=pi(2-4/3+2/5)=6 pi/15

The geometric meaning of using definite integrals:
s=x 2 definite integral on [1,2] = (x 3) 3 difference between the value of the function at x=2 and x=1 = 7 3
The formula for calculating the volume of the rotating calendar:
v= x 2) 2] definite integral on [1,2] = x 5) 5 difference between the value of the function at x=2 and x=1] = 31 5
