Oct 29, 2013 · I recently started thinking about what inverse tangent is. It is obvious that the definition of tangent is $\frac {\sin x} {\cos x}$, however, what is inverse tangent?

Oct 14, 2020 · When calculating the inverse tangent of a degree, the calculator will always give an angle between 90 degrees and –90 degrees. But I want to find the positive value of the negative angle. Do …

Apr 11, 2020 · Whenever I calculate inverse tangent on the calculator it only gives the correct angle when the point (X, Y) is in the first and fourth quadrant. Whenever the point lies in the second or third …

Jan 27, 2017 · Yes, tangent is negative in quadrant IV and II, but the range for arctan is limited to $\frac {-\pi} {2}\le {y}\le\frac {\pi} {2}$ so our angle cannot lie in quadrant II. It must lie in either quadrant I or …

It is NOT the tangent function! It's the inverse. What value of x makes tan (x) go to infinity?

Jun 10, 2016 · Why is the inverse tangent function not equivalent to the reciprocal of the tangent function? Ask Question Asked 9 years, 6 months ago Modified 9 years, 6 months ago

Sep 2, 2015 · tan − 1 denotes the inverse tangent function, AKA the arc tangent (the angle the tangent of which is the given number). When applied to an argument, you spell tan − 1(x) = arctan(x).

Dec 31, 2015 · Another answer. In complex analysis, each of these inverse trig functions may be written in terms of the complex (natural) logarithm. So take that definition, and use the principal value of the …

Apr 22, 2013 · My textbook gives me this: Can someone please walk me through the steps to get -pi/3 from the inverse tangent?

In that case we define two things for $\tan$: the reciprocal function $\cot $ that is really defined by $\cot (x) = 1/\tan (x)$ and the inverse function $\arctan$ given by the property I've mentioned above. Take …
