2/3 - 1/2 as a fraction
2/3 - 1/2 as a fraction- 1/2 equals 05, meaning B's also not it We also know the answer isn't D, since 0 does not equal 1 That only leaves C Yet when check, just in case, √3/2 equals , meaning that's not the answer We've eliminated every answer so far, meaning we should go back and check our workQuestion If the terminal side of an angle θ in standard position intersects the trigonometric circumference at the point P (−1 / 2, √3 /

Next consider 30° and 60° angles In a 30°60°90° right triangle, the ratios of the sides are 1 √3 2 It follows that sin 30° = cos 60° = 1/2, and sin 60° = cos 30° = √3 / 2 These findings are recorded in this table If i = √(1) then 4 5(1/2 i√3/2) 334 3(1/2 i√3/2) 365 is equals to (a) 1 – i√3 (b) 1 i√3 (c) i√3 (d) i√3 Answer Answer (c) i√3 Given, 4 5(1/2 i√3/2) 334 3(1/2 i√3/2) 365 = 4 5w 334 3w 365 {since w = 1/2 i√3/2} = 4 5w 3w² {since w³ = 1}Determine angle type 74 is an acute angle since it is less than 90° sin (74) =
(√31)/(√3–1) = ab√2 In this sum it should be ab√3, not ab√2 (√31)/(√3–1)=ab√3 => (√31)(√31)/(√3–1)(√31)=ab√3 => (√31)^2 What is the coordinate points of (1/2,√3/2) when reflected to quadrant 3?Cot(21) = Write cot(21) in terms of tan Since 21° is less than 90, we can express this in terms of a cofunction cot(θ) = tan(90 θ)
