In the following, we are integrating a function f : 0 - R over its domain. In particular, suppose we know that $ is x-simple, and indeed, If(z, y) dady =[ f(z, y) da dy + f(x, y) da dy. -2vy+1 Note: Remember to write your answers using Matlab syntax. For example, 3 7 + V2cT + 3e4 would be written as (x - 2e)2 x* (1/3) + (sqrt (2*x*pi+3*exp (4*x) ) / (x-2*exp (1) ) *2 By sketching $, or otherwise, one can see that $2 is also y-simple, and that b If(z, 3) da dy = () f(x, y) dy da, where a = b = v(T) =
