"Arc tan sum" refers to the inverse trigonometric function arctan, which is also known as the inverse tangent. It is used to find the angle whose tangent is equal to a given number or ratio.
To solve for "Arc tan sum", you can use a scientific calculator or a trigonometric table to find the inverse tangent of the given number or ratio. Alternatively, you can also use the formula arctan(x) = tan^-1(x) = tan^-1(y/x) to find the angle.
The domain of "Arc tan sum" is all real numbers, while the range is between -π/2 and π/2 radians or -90 and 90 degrees.
"Arc tan sum" is used in various real-life applications, such as in navigation and surveying to find angles and distances, in computer graphics to determine the rotation angles of objects, and in physics to solve problems involving angles and forces.
"Arc tan sum" is related to other trigonometric functions, specifically tangent, sine, and cosine, through the fundamental trigonometric identity arctan(x) = tan^-1(x) = sin^-1(x/sqrt(1+x^2)) = cos^-1(sqrt(1-x^2)), where x is the ratio of the opposite side to the adjacent side of a right triangle.
