  I strongly disagree with the definition itself. And yes, there are stops that prevent me from doing that in scientific computing resources like sympy, matlab, and my professors.

    You disagree that a ratio is unitless? What’s the cos of a unit?

      yep, I don’t think the question “what’s the cos of a unit” is valid because cos expects a plane angle in the input and a unit doesn’t meet that expectation; it’s underdefined; it depends whether the calculator is set to radians or degrees.

        It’s not undefined. You cannot take the exponential of anything with dimensions. That also applied to logs and trigonometric functions. Ergo, angles must be unitless.
