Solving trigonometric equations I: basic equations and general solutions — Homework
Isolate the trig function completely first, then use the unit circle to find every solution in the interval.
- 1.Solve 2cos(x)+1=0 for x in [0,2pi).
- 2.Solve tan(x)=1 for x in [0,2pi).
- 3.Write the general solution for sin(x)=-1/2.
- 4.Solve sqrt(3)*tan(x)-1=0 for x in [0,2pi).
- 5.Explain why sin(x)=-1/2 has two solution families rather than infinitely many unrelated solutions.
