Final answer:
The angle tan^-1(1) rounded to the nearest degree is 45 degrees.
Step-by-step explanation:
The function tan^-1(xs) is the inverse tangent function, also known as arctan, which returns the angle whose tangent is a given value xs in radians. In this case, the given value is 1. To find the angle in degrees, you can use the formula degrees = radians*180/π.
So, tan^-1(1) in radians is equal to π/4. Converting this to degrees, we have degrees = (π/4)*180/π, which simplifies to 45 degrees.
Therefore, tan^-1(1) rounded to the nearest degree is 45 degrees.
