    Richard Feynman found trigonometry notation to be ambiguous and confusing. "If I had sin f, it looked like s×i×n×f" So he decided to create his own notation. See below. 🧐 What do you think?pic.twitter.com/61ByeX7LMz

        Gauss also famously complained that sin² x should mean sin sin x and not (sin x)²

        i actually like this notation, i hate having to specify sin(θ)+y with parens but sin θ + y is ambiguous

        The middle one could easily be confused for 'square root of theta'.

        This notation is just more confusing. Signa, Gamma and Tau are used a lot in physics and this could bring more confusion. Moreover sin() and cos() are written as function, like f(x) or f(x, y, z). They are simply more familiar

        They aren't always written with the parentheses though
