Jul 20, 2009 · If arctan (x) = tan (x)^-1 and since tan (x) = sin (x)/cos (x) is not arctan (x) = cot (x). I know something's not right here but what is it? Thanks.

Dec 12, 2011 · I posted the picture of this question I am just wondering. Why does arctan(n) as n → ∞ go to ∏/2? How would you show that part more in depth? Also what would arccos(n) and arcsin(n) …

Jul 2, 2023 · Let z=x+iy, and w=u+iv. I am looking for a formula to find the arctangent of z, or w=arctan(z). I want the results of u and v to be in terms of trigonometric and hyperbolic functions …

Nov 13, 2006 · Hey guys, I was doing some questions from spivak when i noticed this integral he set up. To prove that the integral is \\pi/2 for all values of x, i needed to prove Arctan(x) + Arctan(\\frac{1}{x}) …

Jan 14, 2014 · I've been looking for this identity: arctan(1/x) = arcot(x) or arccot(1/x) = arctan(x) After just visually inspecting this to be true, I have been unable to find any formal proofs for it. Any references …

Oct 30, 2010 · I can not seem to figure out why Arctanh x [ Hyperbolic Arctan ] can be expressed as Arctanh x = (1/2) [ Log (1+x) - Log (1-x) ] Note; I know the 1/2 means the expression is a square root …

Jun 24, 2005 · \sum_ {i=1}^ {n} \arctan (\frac {1} {2n^2}) I have to find sum of first n terms. I have no idea what to do with these arctan. Give me please any hint.
