The cosine of a vector is equal to the opposite over its magnitude.

If this really is the statement, I would not say it was either "true" or "false". I would just say it is non-sense! The function "cosine" is not [g]defined[/b] for vectors, only for angles or numbers. Further, saying "the opposite" is non-sense. "Opposite" is an adjective not a noun and cannot take the article "the".Tiven white said:Homework Statement

the cosine is the ratio of the adjacent to the hypothenuse this is why i say it "came' is incorrect.

Definitely false.Tiven white said:The question was asking whether the statement ' cosine means the y component of a vector over its magnitude'.
Is this true or false?
The cosine of a vector is a mathematical function that calculates the ratio of the adjacent side of a right triangle to its hypotenuse. It is commonly used in trigonometry to determine the angle between a vector and the horizontal axis.
The cosine of a vector can be calculated by dividing the length of the adjacent side of the triangle by the length of the hypotenuse. This can be represented by the formula cos(theta) = adjacent/hypotenuse.
The cosine of a vector is equal to the cosine of the angle formed between the vector and the horizontal axis. This means that the value of the cosine of a vector is dependent on the angle of the triangle.
The cosine of a vector can range from -1 to 1. A value of -1 indicates that the vector is perpendicular to the horizontal axis, a value of 0 indicates that the vector is parallel to the horizontal axis, and a value of 1 indicates that the vector is in the same direction as the horizontal axis.
The cosine of a vector is used in various fields such as physics, engineering, and computer graphics. It is used to calculate forces, angles, and projections in real-world scenarios. It is also used in navigation and satellite tracking systems.
