WebMar 26, 2016 · How to Calculate the Sine of an Angle. Identify the hypotenuse. Where’s the right angle? It’s. Locate the opposite side. Label the adjacent side. Locate the two sides that you use in the trig ratio. Find the sine. Web6sin (π/2⋅x) = 3. sin (π/2⋅x) = 1/2. From the unit circle, the sine values that equal 1/2 have the solution set x = π/6+2πn, 5π/6+2πn. π/2⋅x = π/6+2πn, 5π/6+2πn. x = 1/3+4n, 5/3+4n. Since we are looking for the 4 smallest positive solutions, we would need to plug in n=0 and n=1: x = 1/3+4 (0), 5/3+4 (0) x = 1/3, 5/3. x = 1/3+4 ...
