Find the Point $( x , y )$ On the Unit Circle That Corresponds to the Real Number

question 53

Multiple Choice

Find the point $( x , y )$ on the unit circle that corresponds to the real number t. (Round your answer to one decimal place.) $$t = \frac { \pi } { 5 }$$

• A) \(t = \frac { \pi } { 5 }\) corresponds to the point \(( 0.8 , - 0.6 )\).
• B) \(t = \frac { \pi } { 5 }\) corresponds to the point \(( - 0.8 , - 0.6 )\).
• C) \(t = \frac { \pi } { 5 }\) corresponds to the point \(( 0.8,0.6 )\).
• D) \(t = \frac { \pi } { 5 }\) corresponds to the point \(( 0.6 , - 0.8 )\).
• E) \(t = \frac { \pi } { 5 }\) corresponds to the point \(( 0.6,0.8 )\).
