Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Please ensure that your password is at least 8 characters and contains each of the following:. Find the first derivative. Replace with in the formula for period. Separate fractions. Take the inverse tangent of both sides of the equation to extract from inside the tangent. Simplify each term. At , the second derivative is. Make the expression negative because cosine is negative in the second quadrant. Split into intervals around the points that could potentially be inflection points. To find the second solution , subtract the reference angle from to find the solution in the third quadrant. Since this is negative, the second derivative is decreasing on the interval. Step 2. To write as a fraction with a common denominator , multiply by.
