60 is an angle of one of the standard triangles with cos 60 1 2 240 is in the 3rd quadrant so either by CAST or noting that the x side of the associate triangle is negative How do you use the sum and difference identities to find the exact value of tan 105 degrees How do you apply the sum and difference formula to solve trigonometric equations How do you evaluate sin 45 cos 15 cos 45 sin 15
1 2 cos 60 0 first convert 60 0 in radians just for the sake of convenience of problem solving in trigonometry since pi radian 180 0rArr 60 0 pi 3 radians now since cos theta costheta so cos pi 3 cos pi 3 1 2 a standard value and should be memorised The best videos and questions to learn about Trigonometric Functions of Any Angle Get smarter on Socratic
