Answer:
Step-by-step explanation:
We want to find the solutions to:
Within the interval [0, 2π).
First, isolate the sine:
Recall the unit circle. This is true twice: at π/4 and 3π/4.
Hence, our solutions are:
If you want to solve the equation
for C, you can work like this: subtract P from both sides:
Add C to both sides:
