Chapter 4, Problem 4.4-5(choose chapter or problem)
For each of the following functions, determine the value of c for which the function is a joint pdf of two continuous random variables X and Y.
(a) \(f(x, y)=c x y, \quad 0 \leq x \leq 1, \quad x^{2} \leq y \leq x\).
(b) \(f(x, y)=c\left(1+x^{2} y\right), \quad 0 \leq x \leq y \leq 1\).
(c) \(f(x, y)=c y e^{x}, \quad 0 \leq x \leq y^{2}, \quad 0 \leq y \leq 1\).
(d) \(f(x, y)=c \sin (x+y), \quad 0 \leq x \leq \pi / 2, \quad 0 \leq y \leq \pi / 2\).
