For which angle is cosθ sinθ
WebExample 1. The acute angle θ as sinθ = 3 5. Find cosθ, tanθ, cotθ, secθ, and cscθ. Answer. We can use any right triangle that has an angle with sinθ = 3 5 to calculate the other trig functions. If we have a right triangle with hypotenuse H = 5, and the leg opposite to θ to be O = 3, then sinθ = O H = 3 5. Such a triangle is shown below: http://scipp.ucsc.edu/~haber/ph116A/Rotation2.pdf

We now solve the following equations: cosθ = 0. 2sinθ + 1 = 0. Each coordinate pair (x,y) on this unit circle represents (cosθ,sinθ) at an angle θ. For cosθ = 0, we see from the unit circle that this holds true for θ = π 2, 3π 2 over the interval ...
