Find one value of x that solves the equation by using the inverse sine or cosine function on your calculator. These functions may be labeled as arcsin and arccos or as sin-¹ and cos¹. Give your answer in radians. Round your answer to three decimal places. a) When sin(x) = -0.49, then x = sin -¹ (−0.49) = -1 b) When cos(x) = 0.28, then x = cos -¹ (0.28) = is one solution. is one solution.
