∫ LNX / 2 for indefinite integral

∫ln(x/2) dx
= xln(x/2) - ∫x*[ln(x/2)]' dx
= xln(x/2) - ∫x*1/(x/2)*(1/2) dx
= xln(x/2) - ∫ dx
= xln(x/2) - x + C

Conversion of liquid volume and gas volume ~ what is the conversion formula of liquid volume and gas volume?
How many cubic meters of LNG can one cubic meter of LNG be converted into?
Sorry, it's wrong.
How many cubic meters of liquefied natural gas can one cubic meter of natural gas be converted into?
Who can tell me how the volume of liquid is equal to the volume of gas? thank you

It is assumed that the density of liquid natural gas is ρ 1 and the volume is V1, while the density of gaseous natural gas is ρ 2 and the volume is v2
The relationship between weight and volume is m = ρ v. according to the principle that the weight remains unchanged before and after conversion, it can be concluded that ρ 1v1 = ρ 2v2
That is: V1 = ρ 2v2 △ ρ 1
So to know how many cubic meters of LNG can be converted from one cubic meter of natural gas, we need to know the density of both

Calculation: (3a + 2b) (3a-2b)=______ ．

The original formula = (3a) 2 - (2b) 2 = 9a2-4b2

The tangent plane equation of surface 3x ^ 2 + y ^ 2-z ^ 2 = 27 at point (3,1,1) is

The tangent plane normal vector (18,2, - 2) of the surface at this point, and the tangent plane equation is (x-3) * 18 + (Y-1) * 2 + (Z-1) * - 2) = 0. The above solution is the normal equation passing through this point
If the normal vector of any plane f (x, y, z) = 0 at point (x, y, z) is (f'x, f'y, f'z), then it has its normal vector, and it is easy to find the tangent plane. F'x means the partial derivative of F to X

If a, B and C are three sides of △ ABC, a + C = 2B, and the equation a (1-x2) + 2bx + C (1 + x2) = 0 has two equal real roots, the value of sina + SINB + sinc is the same

The equation a (1-x2) + 2bx + C (1 + x2) = 0 is reduced to (C-A) x2 + 2bx + C + a = 0 because it has two equal real roots, so C-A ≠ 0, △ = 0, that is, 4b2-4 (C-A) (c + a) = 0, A2 + B2 = C2

In the rectangular trapezoid ABCD, ad is parallel to BC, ab = 1, ad = radical 3, AB is vertical to BC, CD is vertical to BD. the triangle ABCD is folded along BD to make the plane abd vertical and flat
Face BCD
Find: (1) CD vertical ab
(2) Finding the volume of triangular pyramid a-bdc
(3) Whether there is a point n on the line BC, so that an is perpendicular to BD. if there is, the value of BN to BC is requested; if not, please explain the reason

So: (1) CD vertical AB (2) find the volume of a-bdc = the volume of abd-c = (AB * ad / 2) * CD / 3aD parallel BC, ab = 1, ad = radical 3, AB vertical BC, CD vertical BD, so BD = 2, ∠ abd = 60 °, and ∠ DBC = 30 ° C
