Question: Checking condition statement for all x

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

Please Wait...
