Therefore, sin ( 2π 3) = y = √3 2. b) An angle θ = − 5π 6 corresponds to a revolution in the negative direction, as shown. Therefore, cos( − 5π 6)=x=− √3 2. c) An angle θ = 15π 4 = 2π + 7π 4.

Webb14 okt. 2024 · I assume I need to convert #cot(x) + tan(x)# into terms of cosine and sine, then end up with #1/(sin(x)cos(x))#, but I get stuck with how to deal with the rest of the problem from there. Trigonometry Trigonometric Identities and Equations Solving Trigonometric Equations. 1 Answer WebbNow let's introduce the reciprocal functions. The secant is the reciprocal of cosine, and is abbreviated sec. We define sec(x) as. sec(x)=1cos(x). The cosecant is the reciprocal of sine, and is abbreviated csc. We define csc(x) as. csc(x)=1sin(x). Finally, the cotangent is the reciprocal of tangent, and is abbreviated cot. We define cot(x) as ... litherium coin prices
