It is important to note that sin( π 6) = sin(13 6 π) = 1 2 and, while sin−1(1 2) = the conventional principal value π 6 ,, sin−1sin( π 6) = π 6 and. then sin( π 6 +x) = sin( π 6)cosx + cos( π 6)sinx Using the exact value triangle for this angle Then sin( π 6) = 1 2 and cos( π 6) = √3 2 ⇒ sin( π 6 +x) = 1 2cosx + √3 2 sinx Answer link. sin(π 6) = 1 2 And since r=1 in our unit circle, /begin {align*} /sin /left (/frac {π} {6} /right) & = /dfrac {1} {2} (1) // &= /dfrac {1} {2} /end {align*} Using the Pythagorean Identity, we can find the cosine value. sin( 65π) = sin(6π)= 21 How do you evaluate sin( 67π) ? https://socratic. Sin(pi) or cos(pi/2) problem with Matlab. You can say 1/2=Sin (pi/6) 1/2=Sin (30) 1/2=1/2 That’s why it is equal. sin (5pi/6) Ravi Ranjan Kumar Singh 15. Free trigonometric simplification calculator - Simplify trigonometric expressions to their simplest form step-by-step. The sin(pi/6) is 1/2 because at pi/6 radians, we are 1/2 units away from the x-axis. For math, science, nutrition, history, geography, engineering, mathematics, linguistics, sports, finance, music….
