Solve each equation on the interval 0 greater than or equal to theta or less than 2pie.
12) 4 (cos^2) theta - 3 = 0
Please be descriptive I have having difficulties with these types. TY
Just "unwrap" it like you would any other equation.
Add 3 to both sides.
Divide by 4.
. Take the square root.
.
So what values of make or .
Since the answer is both positive and negative, there are answers in all quadrants. Let's start with the focus angle.
We know
So is the focus angle.
In the domain the solutions are...
.
Does that make sense?
