question 92

Multiple Choice

• B) absolute maximum is 1 at \(\theta = \frac { 1 } { 2 } \pi\); absolute minimum is \(- 1\) at \(\theta = \frac { 1 } { 2 } \pi\),
• C) absolute maximum is 1 at \(\theta = \frac { 3 } { 2 } \pi\); absolute minimum is \(- 1\) at \(\theta = \frac { 1 } { 2 } \pi\),
• D) absolute maximum is 1 at \(\theta = \frac { 1 } { 2 } \pi\); absolute minimum is \(- 1\) at \(\theta = \frac { 1 } { 2 } \pi\)
