    Actually

    I'm struggling to integrate

    (sec^2 x) (1+tan^2 x )

    Um I tried

    y=sec^3 x
    dy/dx= 3sec^2 x (secxtanx)

    but that looks wrong lol

    but substitution is the next part to integration. Haven't learnt how to do that yet.

    Is there an alternative way?

    only recognition
    that is what I see when I give you the substitution
    multiply out gives sec2x + tan2xsec2x

    then
    the first lump is the differential of tanx
    then the second lump is the differential of tan3x with 1/3 in front of it
