11. Let X,Y are two continuous random variables with the following joint probability density function f(x,y)={4xy,00≤x≤1,0≤y≤1 otherwise . Find the expected value (E(X)) and the variance (Var(X)) of X. Hint: The expected value for random variable X is given by E(X)=∬R2xf(x,y)dA E(X2)=∬R2x2f(x,y)dAVar(X)=E(X2)−(E(X))2
12 Determine whether the following vector field is conservative. If it is conservative find f such that F=∇f. F(x,y)=(y2−2x)i+2xyj
