please help Find all the solutions of the equations in the interval [0,27]. a) 4 cos2 x 1 = 0 b) 2 sina x + 7 sin x - 4= 0
Find the exact solutions in [0,2). (1-sin(x))^2=3cos^2(x 10. Find the exact solutions in [0,27). (1 – sin(x))' = 3 cos?(x)
trig 5. [5 Points] Solve each equation for EXACT solutions over the interval [0°, 360º) (a) 2 sin 20 = 1 (b) tan8 +1 =V3+ V3cote
Find the exact radian solutions for all which are solutions of the equation. V3+ 2 sin 20 = 0 (4) - Use the quadratic formula to solve for the solutions of the equation in the interval [0°, 360°). Approximate the solutions to the nearest 0.1°. 5sin? x + 2 sin x – 1 = 0
Find all of the EXACT solutions on the interval [0,2T) for the following equations: 1. 4 sec 0 = -8 2. 7 tan20 = 21 3. 2sin 0 + 2cos 0 = -6 Hints: You'll need to square both sides AND use a double angle identity. 4. 2cos(30) + 1 = 0 (no identities needed to solve)
7. Solve each equation for solutions on the interval [0,2-). Find all exact solutions where appropriate. Round approximate answers in radians to two decimal places. In other words if you can find an exact solutions (ie found on the unit circle) write it in exact form. If it's not possible ſie. not on the unit circle) then round to two decimal places. a) 3 cos 0-cos02 b) cos2x-sinx=0 c) cos3x
