Welcome back Galaxy — missed you this week. The problem asks to determine the sign of the product (1) · (2) · (3) · (4) · (5) · (6). The angles are in radians. Step 1: Determine the quadrant for each angle. We use the fact that ≈ 3.14159 and 2 ≈ 6.28318. • 1 radian is in Quadrant I (0 < 1 < /2 ≈ 1.57). • 2 radians is in Quadrant II (/2 ≈ 1.57 < 2 < ≈ 3.14). • 3 radians is in Quadrant II (/2 ≈ 1.57 < 3 < ≈ 3.14). • 4 radians is in Quadrant III ( ≈ 3.14 < 4 < 3/2 ≈ 4.71). • 5 radians is in Quadrant IV (3/2 ≈ 4.71 < 5 < 2 ≈ 6.28). • 6 radians is in Quadrant IV (3/2 ≈ 4.71 < 6 < 2 ≈ 6.28). Step 2: Determine the sign of each trigonometric function in its respective quadrant. • (1): Quadrant I, is positive. • (2): Quadrant II, is negative. • (3): Quadrant II, is negative. • (4): Quadrant III, is positive. • (5): Quadrant IV, is positive (since is positive in Q4). • (6): Quadrant IV, is negative (since is negative in Q4). Step 3: Multiply the signs together. The product of the signs is (+) · (-) · (-) · (+) · (+) · (-). (+) · (-) · (-) · (+) · (+) · (-) = (-) · (-) · (+) · (-) = (+) · (+) · (-) = (+) · (-) = (-) The overall sign of the product is negative. The student's work shows: 1 2 3 4 5 6 + - - + + - = negative This matches our calculation. The value of the expression is negative. The options given are (1) Positive, (3) Zero. Option (2) is likely Negative, and (4) is likely Undefined or another option. Based on the student's work, the answer is negative. The final answer is Negative. Send me the next one 📸
