How can I do this in Mathcad?

Hi,

I am a Maple user and trying to learn Mathcad.

I wrote a couple equations and want to combine those trigonometric functions.

You can see what I am doing in the attached PDF file.

How can I do the same thing in Madthcad?

Thanks,

Luo

You can do some of it. I don't know how to split out the coefficients.

Remember: Mathcad is primarily a NUMERICAL processor, with an abreviated symbolic processor attached.

    Your "expand" operator is not what the "combine" in Maple does. If you read the "combine" result in Maple carefully, you can see it does a lot more than just expand it. Maple get rid of all the high order terms of sine and cosine and convert them all into first order, something like cos(2w1-w2). This very useful in engineering in that it shows how the frequency mixing. Do you know how to do that in Mathcad?

    Thanks
