Without using a calculator, solve each equation below in the domain 0 ≤ x < 2π. Homework Help ✎
sin(x) = –1
2cos(x) – 1 = 0
tan(x) = 1
2sin(x) = 4sin(x) + 1
Reference the unit circle to help solve this problem.
For which angle(s) in the circle does sin(x) = −1.
Solve the equation for cos(x).
For which angle(s) in the unit circle does cos(x) = 1/2?
Refer to part (a).
How would you solve 2m= 4m + 1?
In this case m = sin(x).
