## Cannot play audio in Windows 7 64...

Maple 17

In the application example SignalGeneration, I click on the button "Play Waveform" and get the message "This option is only available on the Windows platform. Your platform is X86 64 WINDOWS". Does it really mean that I won't be able to play audio file in windows 7 64? If not, how can I solve this problem ?

Thank you!

## Get rid of Typesetting:-dotProduct...

Maple

Hello,

I'm simply trying to define a piecewise function but maple inserts some command I can't even find in the help.

f:-x->piecewise(x<-1,3x^2-5,x=-1,5,x>-1 and x<=4,3x+1,x>4);

and I get in blue

## Different answers for the same integral...

Maple

Why is it when I integrate expressions like cos(3*x)^5*sin(3*x)^2, I get this answers in the worksheet mode :

-(1/21)*cos(3*x)^6*sin(3*x)+(1/105)*cos(3*x)^4*sin(3*x)+(4/315)*cos(3*x)^2*sin(3*x)+(8/315)*sin(3*x)

while using the Integration tutor I get:

(1/9)*sin(3*x)^3-(2/15)*sin(3*x)^5+(1/21)*sin(3*x)^7

I know they must be equivalent but it would be nice to have some concistency and also to know how Maple got the first answer.

Anyone has a clue ?

Thanks!

## 2-D plot with context menu...

Maple
I am trying to produce a 2-D plot of the function (sin(x))^2 using the context menu in document mode but Maple returns this error: sin(x)^2 -> Error, invalid input: smartplot uses a 1st argument, f (of type {algebraic, algebraic = algebraic, {set({algebraic, algebraic = algebraic}), list({algebraic, algebraic = algebraic})}}), which is missing It does the same when I change the function. What's wrong? Thanks Stéphane
