Re: Squaring the sine function

[Dima Pasechnik]

Do you mean to say that you'd like to see the graph of the function?

Then do

plot(sin(x)^4,[-2*pi,2*pi])

Hi,

please where is my mistake?

I write to WolframAlpha sin(x)^ and and I get this (It is good for me):

https://www.wolframalpha.com/input/?i=sin(x)%5E4

I write the same to SageMathCloud and and I get this (It is wrong for me):

https://cloud.sagemath.com/projects/e671b1e4-ed43-4cdf-ba6e-190a2a8127c5/files/sinus-exponent.sagews

I need "sin^4(x)".

What am I doing wrong?

Thanks

Hi,

I'm an SMC site admin, so I added code to plot (and also do series
expansion) to your worksheet.

It's also useful to click the "Help" button in the upper right of SMC...

There is no difference between sin^4(x) and (sin(x))^4. They are the
exact same thing.

What are you **really** trying to accomplish?

Or in other words, are you typesetting, or is the sin^4 part of the result of a computation?
