WebThe sine function is negative in the third and fourth quadrants. To find the second solution, subtract the solution from 2π 2 π, to find a reference angle. Next, add this reference angle to π π to find the solution in the third quadrant. 2θ = 2π+ π 6 +π 2 θ = 2 π + π 6 + π Simplify the expression to find the second solution. Tap for more steps...

WebThe Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C It works for any triangle: And it says that: When we divide side a by the sine of angle A it is … 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 ... WebJun 11, 2024 · sin − 1 ( − 3 5) is the angle with its sine ratio equal to − 3 5. Note that angles in the first and the second quadrants have positive sine ratios and angles in the third and the fourth quadrants have negative sine ratios. So, sin − 1 ( − 3 5) must be an angle in the third or the fourth quadrant. how allow camera access
