    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

        That’s pretty clever; but how do you remember which side is divided by which?

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

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

        Why? I use that notation for logarithms and such too. Even for statistics operators like expectation, variance, bias, if any of those quantities are squared I write them with the operator, a 2 in the exponent, then the quantity I'm performing the operator on. It makes sense!

        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

        I’m a huge fan of Feynman (go lectures of physics!) but I think his proposed notation sucks.
