Attached is a diagram to helpon a circle with radius 1 there are two points one is static the other is
distributed evenly on the circle (i dont know the proper english term)
we sign X to be the hypotenuse on the circle
find the density function of the variable X
solution(i partialy understood it)the questions come after the photo
they say that we take x to be an angle from o til pi/2
we scan only the northern hemisphere because its symmetric.
what is the curv graph represents the length of the side "y" as the angle x varies from 0 to 90 degrees
what is t? the various values of y fom 0 to 2
what is the meaning of y<=t? y ranges from 0 to "t" for a specific "t"
why if they say that x should go from o til pi/2? x is the angle BCA
in the probability function they put x fro 0 till arcsin t/2 where t goes from
? Since the triangle ABC is always right-angled at B,
after this step they did the derivative to find the density function
i understand that step
