Without using a calculator, solve each equation below in the domain 0 ≤ x < 2π. Homework Help ✎
sin (x) = −1
2 cos (x) − 1 = 0
tan (x) = 1
2 sin (x) = 4 sin (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).
