The angle is an angle where the values of the six trigonometric functions are known. Because this is the case, add to keep the value the same. Step 2. Use the sum formula for cosine to simplify the expression. The formula states that . Step 3. Remove parentheses. If you want to know what is cos 5pi/6 radians in terms of trigonometry, then navigate straight to the explanations in the next paragraph; what’s ahead in this section is the value of cos 5pi/6: cos5pi/6 = -√(3)/2 cos 5pi/6 = -√(3)/2 cos 5pi/6 radians = -√(3)/2. The cos of 5pi/6 radians is -√(3)/2, the same as cos of 5pi/6 radians in ... Instant Answer. EXPERT VERIFIED. Step 1/2. First, we know that the cosine function has a period of 2pi. This means that cos (x) = cos (x + 2pi*n) for any integer n. …The value of sin 7pi/6 in decimal is -0.5. Sin 7pi/6 can also be expressed using the equivalent of the given angle (7pi/6) in degrees (210°). We know, using radian to degree conversion, θ in degrees = θ in radians × (180°/ pi) ⇒ 7pi/6 radians = 7pi/6 × (180°/pi) = 210° or 210 degrees. ∴ sin 7pi/6 = sin 7π/6 = sin (210°) = - (1/2 ...Trigonométrie. Trouver la valeur exacte cos ( (5pi)/6) Step 1. Appliquez l’angle de référence en trouvant l’angle avec des valeurs trigonométriques équivalentes dans le premier quadrant. Rendez l’expression négative car le cosinus est négatif dans le deuxième quadrant. Step 2.Detailed step by step solution for arccos(cos((-5pi)/6))Explanation: cos( 5π 6) = −cos( π 6). cos( π 6) = √3 2 can be seen from the geometry of a 30,60,90 degree triangle, which is half of an equilateral triangle. Therefore, cos( 5π 6) = − √3 2. Since sin−1( −x) = −sin−1(x), and sin−1( √3 2) = π 3 (which can be seen from the same 30,60,90 degree triangle), sin^ {-1} …Are you tired of overspending on clothes?
