www.math.colostate.eduThe shell is clearly preferable, since the vertical sides will simply run from y= 4 x2 to y= x2 4, whereas for washers the inner and outer sides would both be determined by y= 4 x2 on the top half of the solid and by y= x2 4 on the bottom half of the solid. Since we’re using cylindrical shells and the region runs from x= 2 to x= 2, the volume ...

www.math.colostate.eduThe Laplace transform is defined for all functions of exponential type. That is, any function f t which is (a) piecewise continuous has at most finitely many finite jump discontinuities on any interval of finite length (b) has exponential growth: for some positive constants M and k

math.montana.eduHomework 1 Solutions 1.1.4 (a) Prove that A ⊆ B iff A∩B = A. Proof. First assume that A ⊆ B. If x ∈ A ∩ B, then x ∈ A and x ∈ B by definition, so in particular x ∈ A. This proves A ∩ B ⊆ A. Now if x ∈ A, then by assumption x ∈ B, too, so x ∈ A ∩ B. This proves A ⊆ A ∩ B. Together this implies A = A∩B.
