Hello, I need help on my Mathematics 30-1 Quiz 7.1 (Pre-calculus) Questions #14-#16 and Numerical Response #5

Quiz 7.1 - TS 14. The general solution to the trigonometric equation 2 sin' 0 - sin 0 = 0 is A. 0 = un, 67 1 + 2Tn, n E I 0 = TM, 6 1 1 + 2nn, 6 ST + 2nn, n E I C. 0 = 2Tn, 6 n, + 2un, n E I D. 0 = 2n, 6 ST + 2 nn, n e I It + 2nn, 6 Hint: Factor first. Note there may be several components to the general solution. 15. To solve the trigonometric equation 4 sin 0 - 1 = 3 sin 0, the equation can be rewritten as A . (4 sin 0 + 1)(sin 0 - 1) = 0 B. (4 sin 0 - 1)(sin 0 + 1) = 0 C . (4 sin 0 + 1 )(sin 0 + 1) = 0 D . (4 sin 0 - 1)(sin 0 - 1) = 0 Hint: Write the equation 4 sin 0 - 1 = 3 sin 0 as 4x3 + 1 = 3x, letting x = sin 0, and then factor. Numerical Response 5. To the nearest hundredth of a radian, the solution to the trigometric equation 3 tan 0 + 4 = 0 that lies in quadrant II is Hint: Make sure the calculator used is in radian mode. 16. Which of the following statements about the identity 1 + cosx _ _sinx is not true? sinx 1 - cosx A. The graphs produced by the functions on each side of an identity will be identical. B. The permissible values of the variable always produce identical values on both sides of the equation. C. The non-permissible values of the variable always produce identical values on both sides of the equation. D. Substituting any value for the variable, other than a non-permissible value, results in both sides of the equation being equal. Hint: Refer to proving identities. END OF QU Total Me
