Take the inverse tangent of both sides of the equation to extract from inside the tangent. Divide each term in by. The distance between and is. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Simplify the expression to find the second solution. The period of the function can be calculated using. To find the second solution , subtract the reference angle from to find the solution in the third quadrant. The absolute value is the distance between a number and zero. Since this is negative, the second derivative is decreasing on the interval. The period of the function is so values will repeat every radians in both directions. Combine the numerators over the common denominator.
