SOLVE. integration of (1-v) /(1+v^2)
Marta_Voda [28]
I think you have to first separate the integral:1/(1+v^2) + v/(1+v^2),
so the integral of the first term is ArcTan (v) and for the integral of the second term i recommend you to do a change of variable:

y= 1+v^2
 so
 dy= 2v
 and
v= dy/2and then you substitute:v/(1+v^2) = (1/2)(dy/y)
and the integral is
 (1/2) (In y)finally you plug in the initial variables:

(1/2)(In [1+v^2])

so the total integral is:

ArcTan (y) + (1/2)(In [1+v^2])

Where does the length of day remain the same throughout the year?
djyliett [7]
Due to the inclination of the terrestrial axis, the day has different duration in several points of the planet, which also depends on the time of year. However, this duration remains the same throughout the year in the Equator, which is known as the imaginary line that divides the planet in two hemispheres: Northern Hemisphere and Southern Hemisphere.

A square notepad has sides that are 10 centimeters long. What is the notepad's area?
blsea [12.9K]

Answer:

100cm²

Step-by-step explanation:

The notepad is square.

The area of a square = length X width.

All the sides of a square are the same length.

Therefore, the area of the notepad = 10 X 10 which equals 100.

Don't forget the units!

The units for area is cm².

The units for volume is cm³.

This is area so your answer is 100cm².

Hope this helped, have a nice day!
