WebFeb 1, 2024 · Solve: 3sin^2 x - 2cos^2 x = 4sin x + 7 (0 < x < 2Pi). Solution. Replace in the equation (cos^2 x) by (1 - sin^2 x), then simplify the equation: 3sin^2 x - 2 + 2sin^2 x - 4sin x - 7 = 0. Call sin x = t. The equation becomes: 5t^2 - 4t - 9 = 0. This is a quadratic equation that has 2 real roots: t1 = -1 and t2 = 9/5. WebThe value of sin 7pi/12 can be calculated by constructing an angle of 7π/12 radians with the x-axis, and then finding the coordinates of the corresponding point (-0.2588, 0.9659) on …
WebRotate ‘r’ anticlockwise to form 7pi/4 angle with the positive x-axis. The tan of 7pi/4 equals the y-coordinate (-0.7071) divided by the x-coordinate (0.7071) of the point of intersection (0.7071, -0.7071) of unit circle and r. Hence the value of tan 7pi/4 = y/x = -1 ☛ Also Check: sec pi/2 sin 5pi/12 csc pi/3 tan 5pi/4 tan pi/4 cos pi/2 WebProof: x = 2tan20+tan50 = 2cos20cos50sin(20+50) = 2cos501. y = 2tan20+tan70 = 2cos20cos70sin(20+70) = sin401 = cos501.
