If cos theta is less than 0

Web14 apr. 2015 · Apr 14, 2015. The answers are: sinα = √5 5, cosα = 2 √5 5. First of all, if the sinus and the tangent of an angle α is positive, the angle is in the first quadrant and so sinus and cosine are positive! Since tanα = sinα cosα, than: sinα cosα = 1 2. and, for the fundamental relation of trigonometry: WebPrecalculus. Find the Trig Value sin (theta)=2/5. sin(θ) = 2 5 sin ( θ) = 2 5. Use the definition of sine to find the known sides of the unit circle right triangle. The quadrant determines the sign on each of the values. sin(θ) = opposite hypotenuse sin ( θ) = opposite hypotenuse. Find the adjacent side of the unit circle triangle.
