Question 42

Multiple Choice

Use a calculator to demonstrate the identity for the value of θ.​ sin⁡(−θ) =−sin⁡θ,θ=258∘\sin ( - \theta ) = - \sin \theta , \theta = 258 ^ { \circ } ​


A) ​ sin⁡(−258∘) =−sin⁡258∘≈0.9781\sin \left( - 258 ^ { \circ } \right) = - \sin 258 ^ { \circ } \approx 0.9781
B) ​ sin⁡(−258∘) =−sin⁡258∘≈1.0081\sin \left( - 258 ^ { \circ } \right) = - \sin 258 ^ { \circ } \approx 1.0081
C) ​ sin⁡(−258∘) =−sin⁡258∘≈0.9981\sin \left( - 258 ^ { \circ } \right) = - \sin 258 ^ { \circ } \approx 0.9981
D) ​ sin⁡(−258∘) =−sin⁡258∘≈−0.9781\sin \left( - 258 ^ { \circ } \right) = - \sin 258 ^ { \circ } \approx - 0.9781
E) ​ sin⁡(−258∘) =−sin⁡258∘≈−0.9981\sin \left( - 258 ^ { \circ } \right) = - \sin 258 ^ { \circ } \approx - 0.9981
