A fraction divided by an integer (except 0) equals______ .

A fraction divided by an integer (except 0) equals______ .

A fraction divided by an integer (except 0) is equal to multiplying by the reciprocal of the integer
From v = 2 pies R / T (linear velocity) w = 2 pies / T (angular velocity)
It can be concluded that
W times r = v
I know that Pai is 180 degrees in w = 2 Pai / T (angular velocity), but Pai is 3.1415926 in v = 2 Pai R / T (linear velocity)?
You haven't learned the radian system yet
"Radian system" replaces "angle system" in trigonometric function
In a circle, the arc of a central angle pair is several times the radius, and the angle is just how big, and the unit is rad
180 degrees is a semicircle, semicircle = pie * radius
So the 180 degree angle is PRAD
That's right
This place is a little out of touch
Physics was used before mathematics was learned
If the base of a triangular pyramid is an equilateral triangle whose side length is root 2 and the side is an congruent right triangle, then the volume of the triangular pyramid is?
Bottom area = root 3 / 6
High = root 3 / 3
Volume = 1 / 18
According to the solution of V = SH / 3, the volume of root 2 is obtained
Such a simple question
Bottom area = root 3 / 2
High = root 3 / 3
Volume = 1 / 6
I need a lot of fifth grade volume II fraction equation solving exercises, as long as the fraction addition and subtraction method,
x+3/7=3/4 X-5/12=3/8 X-5/6=1 1/3-X=2/5 4X+2/5=3/5 3X-X=1 x+1/5-1/10=1/22x+4x-1/4=3/4 x-5/8=3/4 x+2/7=3/7 3/5-2x=3/5 1/2+1/4+X=1
Formula of angular velocity
Angular velocity formula: ω = Φ / T = 2 π / T = 2 π f
explain:
ω. Circular frequency, also known as angular velocity
Φ, angle,
t. Time
π. PI
T. Cycle
F, frequency
If the base side of a regular triangular pyramid is 2 and the sides are right triangles, the volume of the regular triangular pyramid is______ .
The length of the bottom side of a regular triangular pyramid is 2, and the sides are all right triangles. It can be seen that the length of the side edges is 2, and the three sides are perpendicular to each other, so the volume of this triangular pyramid is 13 × 12 × 2 × 2 = 23, so the answer is: 23

8/9+3/9=? 2/3+2/6=? 69/124+55/124=? 8/25+69/100=? 1/32+7/47=?
What is the relationship among angular velocity, linear velocity and rotational speed in physics? How to transform each other?
Thank you
Uniform circular motion 1. Linear velocity v = s / T = 2 π R / T 2. Angular velocity ω = Φ / T = 2 π / T = 2 π f ω × r = v3. Centripetal acceleration a = V2 / r = ω 2R = (2 π / T) 2R 4. Centripetal force fcenter = MV2 / r = m ω 2R = MR (2 π / T) 2 = m ω v = f 5
If the base side of a regular triangular pyramid is 2 and its sides are right triangles, the volume of the pyramid is
Method 1
The right side length of a right triangle is radical 2, so the volume is radical 2 * radical 2 * radical 2 * (1 / 6) equals (radical 2) / 3, so the height is radical 2
Method 2
Taking the vertex as the origin, the space rectangular coordinate system is established, and the distance between points and surfaces is calculated
In addition and subtraction of fractions with different denominators, the denominator should be divided, so as to ensure that () is filled in the blank
Guarantee (it is the same denominator, so that it can be added or subtracted)
