Mike Truong WeBWorK @ Dept of Mathematics and Statistics @ SDSU WeBWorK problems. WeBWorK assignment 08IntegralsImproperRcg due 02/29/2008 at 09:00am PST. 1. (1 pt) Find the area under the curve y = 1 / ( 8 x 3 ) from x = 1 to x = t and evaluate it for t = 10 , t = 100. Then ﬁnd the total area under this curve for x ≥ 1. (a) t = 10 (b) t = 100 (c) Total area Correct Answers: • 0.061875 • 0.06249375 • 0.0625 2. (1 pt) Determine whether the integral is divergent or con-vergent. If it is convergent, evaluate it. If not, state your answer as ”divergent.” Z ∞0 4 e-x dx Correct Answers: • 4 3. (1 pt) Determine whether the integral is divergent or con-vergent. If it is convergent, evaluate it. If it diverges to inﬁnity, state your answer as ”INF” (without the quotation marks). If it diverges to negative inﬁnity, state your answer as ”MINF”. If it diverges without being inﬁnity or negative inﬁnity, state your answer as ”DIV”. Z
