Question
Consider the following equation.
7cos(x) - 8 = 9cos(x) -7
(a) Solve for all degree solutions. Use a calculator to approximate all answers to the nearest tenth of a degree. (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°. Use a calculator to approximate all answers to the nearest tenth of a degree.
?1 = °
?2 = °
?1 = ° + °k
?2 = ° + °k
(b) Solve for ? if 0° ≤ ? < 360°. Use a calculator to approximate all answers to the nearest tenth of a degree.
?1 = °
?2 = °
