How many true solutions does the equation sin x= cos x 1 have over the interval I] 5 x 5 2x ? O A. one 0 B. two 0 C. three 0 D. four The equation 3sin x + cos x = 2 is solved below. 3sin x + cos x = 2 3sin x + (1-sin x) =2 3sin x - sin x+1=2 3sin x - sin x-1=0 sin x - 3sin x +1= 0 (sin x - 3)(sin x +1) = 0 sin x - 3= 0 or sin x +1= 0 sin x = 3 or sin x = -1 x = sin (3) or x = sin (-1) X= -+ 2n7 3 Which of the following best describes the solution? O A. The Pythagorean identity was applied incorrectly. O B. The equation was factored incorrectly. O C. The inverses were taken incorrectly. O D. There is no error in the solution.If 2 tan x- sec x = 1, which of the following are true? Select all that apply.
