I have been trying to work on this worksheet and i am having avery hard time i understoook number 2 and 3 but i can't seem tofigure out the rest
Investigate whether the series 1/2 - n 3n - 1 is convergent. If so, find its sum. Consider the series 1/n2 + 1. Use the following convergence tests to determine whether it is p prove that the series is convergent or not The comparison test, or the limit comparison test The integral test The ration test Test the convergence of 2n2 + 3n/ . Use an appropriate convergence test to investigate the convergence of the following series: Find the radius and interval of convergence of the series n(-1)n/4n(x + 3)n. Use Series to find lim x rightarrow sin(x) - x/x3. Then use L'Hospital rule to check your answer. Using power series, evaluate the integral x cos(x4) dx
