This four term equality has all four of its arctan terms positive , the numerator term in the arctan is always equal to unity, and M≥38. We have used an on-line calculator to verify this result to over 1000 decimal places. The disadvantage of multiple arctan formulas is the need to sum multiple sums. To get around

The domain for the arctan is all real numbers with the range- < y < /2. The arctan will return the values the same way the inverse sine returns values, in the first and 4th quadrants. Examples for calculator problems. Find the answers in radian measure. Set calculator mode to rads. 1) Cos-1 (-.5) = 2.09 rounded to nearest hundredth.

Using your calculator look at the graph of the functions f(x)=sin x and f(x)=sin(4x). ... We use the names sin-1, cos -1 , and tan-1 or arcsin, arccos, and arctan to represent the inverse of these functions on the limited domains you explored above. The values in the limited domains of sine, cosine and tangent are called principal values. ...
