Question

Choose the values that would complete the general solution for y= arctan (0.7002).

(blank)+360k degrees
-215
-35
-145
-325

Answer 1

-145°, -325°

Explanation:

The principal value of the arctangent of 0.7002 is 35°. The tangent function is periodic with a period of 180°, so the general solution is ...

y = (35 +180k) degrees . . . . . where k is an integer

Values from the given list include ...

-145°

-325°

_____

Additional comment

+35° and +215° would also be part of the general solution
