> Well, there is a "x-¹" button which does the same as Ctrl+I…
See, this button is very misleading. I never thought, that "x" could also stand for a function and not only for a number. You have one button that does completely different things. 2⁻¹ => 0.5 sin⁻¹0.5 => 30 sin²30 => 0.25 and: sin⁻²0.5 => 900 The last one is very questionable, there are only 2 possible interpretations for sin⁻²0.5: Either 1/(sin²0.5) or arcsin(arcsin(0.5)), but not a mixture of both concepts (multiplicative inverse and compositional inverse). >> Allowing arcsin to be entered manually would be nice as well. > Yes, I agree.

Ok, sounds good. >> I'd like to add, that sin⁻¹(x) is not a very nice notation because it >> conflicts with sin²(x) witch, I think, is much more common. > Actually I do think it is ok as it is, IMO most people will read > sin⁻¹(x) as arcsin and sin²(x) as the square of the function value -- I agree, that most people would recognize it correctly.

If you write sin λ without the parentheses, sin λ² would too much look like sin(λ²). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/817709 Title: missing buttons: pi, arcsin, arccos, arctan, arsinh,...
