In other words, trigonometric equations may have an infinite number of solutions. the period of both the sine function and the cosine function is 2π. in other words, every 2π units, the y values repeat, so sin(θ) = sin(θ ± 2kπ). if we need to find all possible solutions, then we must add 2πk, where k is an integer, to the initial solution. Example 7.5.3b: solving a trigonometric equation involving cosecant. solve the following equation exactly: cscθ = − 2, 0 ≤ θ <4π. solution. we want all values of θ for which cscθ = − 2 over the interval 0 ≤ θ <4π. cscθ = − 2 1 sinθ = − 2 sinθ = − 1 2 θ = 7π 6, 11π 6, 19π 6, 23π 6. analysis.
