Determine whether or not F is a conservative vector field. If it is, find a function f such that F=∇ f. F(x,y)=e^xsin y i e^xcos y j(∂(e^xsin y))(∂y)=e^xcos y=(∂(e^xcos y))(∂x) and the domain of F is ^2. Hence F is conservative so there exists...
Determine whether or not ∫ _1^(∞ )e^(-x^2) converges.相关知识点: 试题来源: 解析Since ∫ _1^(∞ )e^(-x) converges and e^(-x^2)≤ e^(-x), ∫ _1^(∞ )e^(-x^2) converges by the Comparison Test.Although there is no elementary function whose derivative is e^(-x^2...
