WebbIn this problem, we are looking at evaluating the formula sign of the difference of arc sine of zero. Subtract our co sign of zero. So we're going to simplify this out with our values and we end up with sign of And for this case, I'm just going to say to buy subtract Hi over to Which in turn ends up being a sign of three pi over two and Sign of three Pi over two … Webb14 apr. 2024 · 1 Answer. Well, you can convert the arctan to other inverse-trig functions, such as arcsin: arctan ( a tan ( x)) = arcsin ( a sin ( x) cos ( x) 2 + a 2 sin ( x) 2) Thanks, … WebbThe derivative of arctan x is 1/(1+x^2).
