... have expressed a double integral as an iterated integral, we can then evaluate it by calculating two single integrals INTRODUCTION Suppose that f is a function of two variables that is integrable ... dx ∫ h( y ) dy since ∫ b a g ( x) dx is a constant Equation ITERATED INTEGRALS Hence, in this case, the double integral of f can be written as the product of two single integrals: b d a c g ( ... ITERATED INTEGRALS Example ITERATED INTEGRALS Example ITERATED INTEGRALS To be specific, suppose that: f(x, y) = g(x)h(y) R = [a, b] x [c, d] ITERATED INTEGRALS Then, Fubini s Theorem gives: d b c...
... does not exist See Example in Section 1.3 So, f is discontinuous at 1.5 P14 Example 2( c) SOLUTION Here, f (2) = is defined and x2 − x − ( x − 2) ( x + 1) lim f ( x) = lim = lim x 2 x 2 x 2 ... P 12 Example 2( a) SOLUTION Notice that f (2) is not defined So, f is discontinuous at Later, we’ll see why f is continuous at all other numbers 1.5 P13 Example 2( b) SOLUTION (b)Here, f(0) = is ... x 2 x 2 x 2 = lim( x + 1) = x 2 exists But lim f ( x) ≠ f (2) x 2 So, f is not continuous at 1.5 P15 Example 2( d) SOLUTION f ( x) = § x ¨ The greatest integer function has discontinuities at...
