Question
Consider the following equation.
2sin2(x) + 9sin(x) = -4
(a) Solve for all degree solutions. Do not use a calculator. (Enter your answer in the form a + bk, where a [0, 360°), b is the smallest possible positive number of degrees, and k represents any integer.
?1 = ° + °k
?2 = ° + °k
(b) Solve for ? if 0° ≤ ? < 360°.
?2 = °
?1 = ° + °k
?2 = ° + °k
(b) Solve for ? if 0° ≤ ? < 360°.
?2 = °
