arctan

we used arctan to find the angle of elevation to the top of the mountain.

the arctan of zero is always zero degrees.

calculating the arctan of a large number results in an angle close to 90 degrees.

the arctan function is the inverse of the tangent function.

we can use arctan to solve for the angle in a right triangle given the opposite and adjacent sides.

the arctan function is useful in navigation for determining bearing angles.

the arctan of -1 is -45 degrees.

the calculator has an arctan function, often labeled as "atan" or "tan⁻¹".

we need to ensure the angle is within the principal value range when using arctan.

the arctan function provides a unique angle for each input value.

the slope of a line can be found using arctan of the rise over run.
