Problems, once again.
1. Compute the average value of:
f(x} = x/(x+3) over the interval [-a,a]
2. Find the area of the region bounded by the graph of:
y = 2√(x^2 + 1)
Line x = 1
On the first, integrate, then divide the integral by 2a.
On the second, integrate with respect to x from x=0 to x=1
INT y dx= INT 2√(x^2 + 1) dx
