Hello, I would like to know if you can help me with this problem the intergal of (cos (6x)+1), I’ve understood it as far as cos (1/2 (ax)) but where is the sqrt of 2 coming from?! Thank you.

  • Calculus -

    integral of (cos (6x)+1) dx ??? from where to where or indefinite?
    anyway if you do not have a typo, that is the sum of two integrals
    cos 6x dx + 1 dx

    (1/6) sin 6x + x + c

  • Calculus -

    Definite

  • Calculus -

    I mean indefinite

  • Calculus -

    from where to where then and what is the a in (1/2)ax ?
    Please check what you typed carefully.

  • Calculus -

    Well, I did the indefinite integral and have no idea where your a and your square root come from.
    There is something your are not telling us.

  • Calculus -

    I have a photo of it, is there a way that I can post it on here?!
