Answer:
sin -115° = -0.91
Step-by-step explanation:
Point A is (cos 115°, sin 115°). Since cos 115° = -0.42 and sin 115° ≈ 0.91, it means that the coordinates at point A is (-0.42, 0.91).
As for point B which was revolved around -115°,
the coordinates will be similar to point A but you just have to change the negative.
B(cos -115°, sin -115°) = B(0.42, -0.91)
For this case we have to rewrite the given expression algebraically:
the cube of a, is represented as:
the square of b, is represented as:
Thus, the product of both expressions is:
And twice the product is represented as:
