The half angle formula: cos (θ/2) = ±√ ( (1 + cosθ)/2). Since sinθ = 3/5, cosθ = 4/5. Therefore, (1+cosθ)/2 = 9/10, and cos (θ/2) = ±√.9. Since 0 < θ < π, we …

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.

WebTheta, cosine of theta is equal to negative one when we're at this point on the unit circle. So that happens when we get to pi radians, and then it won't happen again until we get to two pi, three pi radians, three pi radians. And it won't happen again until we go to two pi, until we add another two pi, until we make one entire revolution, so ...
WebMar 22, 2016 · For question #1 you need to use the formula: sin θ = sin a θ = { 2 k π + a, k ∈ Z or 2 k π + π − a, k ∈ Z. and in the second case. cos θ = cos a θ = 2 k π ± a, k ∈ Z. In our example, in the first case a = 99 π / 5. Take advantage of the inequality to find all the appropriate k ∈ Z in order to define θ.
