If U1 and U2 are i.i.d. Unif(0,1) with U1 = 0.25 and U2 = 0.25, use Box–Muller to generate two i.i.d. Nor(0,1) realizations.
This should generate two different Z1 and Z2 values.

1. If U1, U2, U3 are i.i.d. Unif(0,1), what’s the distribution of ? 2. If U and V are i.i.d. Unif(0,1), what’s the distribution of + ? -3ln(U1(1- U2)(1 - U3)) -2 cos(2TV)-In(U)) n(U) sin(2T V) -3ln(U1(1- U2)(1 - U3)) -2 cos(2TV)-In(U)) n(U) sin(2T V)
The angle between two vectors u1=x1i+y1j+z1k and u2=x2i+y2j+z2k can be determined by cos()=(x1*x2+y1*y2+z1*z2)/(|u1|*|u2|), were |u1|=sqrt(x1^2+y1^2+z1^1). Given...
The angle between two vectors u1=x1i+y1j+z1k and u2=x2i+y2j+z2k can be determined by cos()=(x1*x2+y1*y2+z1*z2)/(|u1|*|u2|), were |u1|=sqrt(x1^2+y1^2+z1^1). Given the vectors u1=3.2i-6.8j+9k and u2=-4i+2j+7k, determine the angle between them (in degrees) by writing one MATLAB command that uses element by element multiplication and the MATLAB built in functions acosd, sum, and sqrt. This is what I tried but i don't think it's correct because it should be one value and I got a vector u1=[3.2 -6.8 9] u2=[-4 2 7] theta=acosd(sum(u1.*u2)./sqrt(u1).*sqrt(u2)).

1) In this exercise, we are given the distribution of Sn=U1+U2+…+Un, where Ui are i.i.d. Uniform(a=0,b=1) random variables. a) Find the p.d.f. of S3=U1+U2+U3 and sketch its graph. b) Find the p.d.f. of S4=U1+U2+U3+U4 and sketch its graph c) Neither S3 or S4 are distributions with a name, but if you sketch their p.d.f.s, they should resemble a previous distribution. Which one?
