Cos theta 2/3 find theta
WebJul 16, 2015 · Determine the general solution of the trigonometric equation: sin θ = 3 cos θ. So the first thing I think of doing when seeing this is making sure either side has the same ratio. I can do this using co-ratios, so: sin θ = 3 sin ( 90 ∘ − θ) sin θ = 3 cos θ. From here I get stuck; there are no values to compute a reference angle with. WebAll steps. Final answer. Step 1/3. − 2 3 cos ( 3 θ) = 1. Multiply both sides of the equation by − 3 2. − 3 2 ( − 2 3 cos ( 3 θ)) = − 3 2 × 1. Simplify both sides of the equation. cos ( 3 θ) …

WebBecause the angle pi/4 is when the area stops being bounded by the first circle (r = 3 sin theta) and starts being bounded by the second circle (r = 3 cos theta). With the first integral, he is trying to measure the red area, which is bounded by the first circle (r = 3 sin theta) from angle 0 to pi/4.
