    cos(sinx)

    can anyone give a result for this integration

    ∫cos(sin(θ)) dθ

    unlimited or limited by any values may reduce any complexity

    integrate cos(cos x)

    I highly doubt that there is a finite expression of that integral. It can be expressed by a series if certain integration limits are applied.

    integration sin(sin(x))

    Hi,
    If this integral has limits of 0 to pi it will be equal to pi*J(0,x) where J(0,x) is Bessel function of order zero.
    Regards,

    integrate cos(cos(x))

    cos(sinx)= cos(cos(90-x))=cos^2(90-x)

    i.e ∫cos˛(90-x)dx which can be ∫ed easily right.

    integral sin catalan

    Hi,
    This is not correct because cos(cos(90-x) is not equal to cos^(90-x) whis is equal to cos(90-x)*cos(90-x).
    It can only be integrated numerically unless it has limits of 0 to pi where it's Bessel function..
    Regards,

    cos integrates to sin

    right
    cos(cos(x)) doesn't equal to cos^2(x)
