Let f(x,y)=e^(−5x)sin(3y).
(a) Using difference quotients with Δx=0.1 and Δy=0.1, we estimate
fx(3,2)≈
fy(3,2)≈

(b) Using difference quotients with Δx=0.01 and Δy=0.01, we find better estimates:
fx(3,2)≈
fy(3,2)≈

Question about using the convolution of distribution: 1. we have the formula: integral fx(x)fy(z-x)dx=integral fx(z-x)fy(x)dx I know this are equivalent. However, how do I decide which side I should use ? For example,X~Exp(1) and Y~Unif [0,1] X and Y independnt and the textbook use fx(z-x)fy(x)dx. However, can I use the left hand side fx(x)fy(z-x)dx???is there any constraint for using left or right or actually both can lead me to the right answer??? 2. For X and Y are independent and...
