To determine The sign of the given trigonometric functions. Explanation Result used: All functions of first-quadrant angles are positive. Sin θ and Csc θ are positive for second-quadrant angles and the rest of the functions are negative. Tan θ and Cot θ are positive for third-quadrant angles and all other functions are negative. Cos θ and Sec θ are positive for fourth-quadrant angles. All others are negative. Calculation: The given trigonometric functions are csc ( − 200 ) ° and cos ( 550 ° ) . Express the function csc ( − 200 ) ° as follows. csc ( − 200 ) ° = − csc ( 180 ° + 20 ° ) Observe that the given angle is in the third quadrant where the csc function is negative
