    I just had a midterm for my calc class and there was this one question that I spent a good 20 minutes on and could not figure out. can someone help me with the solution please?
    lim x→0 (sin x²)/sin²x

    I can do it using L'Hopitals rule, but that wasn't allowed :uhh:

    lim x→0 (sin x²)/sin²x = lim x→0 [(sin x²)/x²][x²/sin²x]
