How to solve trig equations for x
WebThe process is somewhat confusing to find the exact value, but here it is: Let x = 18° (therefore 5x = 90°) sin (3x) = cos (90° - 3x) = cos (5x - 3x) = cos (2x) sin (3x) = cos (2x) (Remember that x = 18°, so that is why this is true.) 3sin (x) - 4sin^3 (x) = 1 - 2sin^2 (x) (I expanded these.) Let y = sin (x) 4y^3 - 2y^2 - 3y + 1 = 0 WebFeb 4, 2024 · c o s ( θ 1) = v 1. s i n ( θ 2) = u 2. c o s ( θ 2) = v 2. And hence according to trig identities, u 1 2 + v 1 2 = 1 (3) u 2 2 + v 2 2 = 1 (4) substituting (3) and (4) in the original equations, I obtained, a 2 2 v 2 2 + a 1 2 v 1 2 − 2 X a 2 v 2 = a 1 2 − X 2 (Equation 5)

WebFirst, re-write the equation so that it is equal to zero: Now we can use the quadratic formula to solve for x. In this case, the coefficients a, b, and c are a=1, b=2, and c=-3: simplify. This gives two potential answers: and. Sine must be between -1 and 1, so there are no values of x that would give a sine of -3. The only solution that works is .
