comment Problem with working precision
@niren but inside the input field you cant do any calculations just input a number. You have to explain exactly what you want.

@niren This is closer to what you really want: InputField[Dynamic[ToString@NumberForm[b, {4, 2}]], String]

comment data visualization on a lattice grid
@dbm that's strange, have you tried selecting the cell and go to the File menu option and select from there the choice "save selection as ..."?

comment Function giving negative value when it should be positive
I tried both the initial integral and the series you give for your provided values and get the same result $0.31644$ if you get $-0.31644$ the I think that @JonathanShock hit the spot.

@J.M. it depends on what the first version of the command was. For instance if the initial plan was to use {1,Tan[th]} to give an example. But I think I will leave it for anyone that cares for a short 101 in trigonometry.

@DavidCarraher the OP mentions an arrow inside a circle but its a good idea.

comment Is there a way to show the details of a numerical computation?
Try ... Trace.

comment MathKernel.exe capped to use only 13% of CPU?
13% means that it uses the 100% of one of your 8 cores (or one of the thread in case of hyperthreding). Some core functions of Mathematica might use more than one core but if you want actively to use more cores you might need to enable this functionality and use commands that can parallelize. Look at the manual for parallelize for more. There is a tab at Mathematica's options panel dedicated to parallelization look there too.
