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])

Answer:
200 students are boys and rest of 400 are girls
Step-by-step explanation:
Given that:
Total students = 300
1/3 students of total are boys
so.
Boys = 1/3(600)
Boys = 200
For finding number of girls:
Girls = total - boys
Girls = 600 - 200
Girls = 400
i hope it will help you!
