1. Complete the table for the sine, cosine and tangent for the special angles in quadrant I. Keep your answer with radical if any. 3 sin x cos a tan a 1 1 1 and the table above to complete the table for cotangent, secant and cosecant for the special angles in quadrant I. Keep your answer with radical if any. cos E 2. Use the identities cot r sec x = csc a = sin x tan a cos a sin a cot a sec a Csc a 3. Determine the sign (positive or negative) of each trigonometric function for the angles in various quadrants. Put + or - to complete the table: sin z Cos a tan x cot a sec x Csc x QI QI QII QIV 197 4 Follow the example and find the exact value for the given trigonometric functions For example sin i) the reference angle is 6 i) sin () = 197 iii) is in quadrant III; hence, sine is negative 6 197 = - sin 1 Therefore, sin 2 Now, please follow the example and complete: 11T a) sin (學) 157 b) Cos 137 c) tan 3 d) cot (- *) 6 237 e) sec 19T CSC
