I have an assignment that I am suppose to be doing in maple, I am suppose to plot the function f(x)=e^(x/3)sin(2x) for abs(x)<=2.... for part of it...

Ive tried multiple things in maple such as plot(exp((1/3)*x)*sin(2*x), abs(x) <= 2) but it keeps throwing me an error, any insight on how to get tis graph plotted would be great.

Hi all,

I am trying to check a conditional statement in maple, I know it is true but my teacher has us do the entire assignment in maple. I am proving the alternating series test of convergence for a series and need to show that the Un's are all positive so

I am trying to check this statement for truth:

5/sqrt(x+4) > 0 for all real values x > 1
