I know how to find the cos(theta) between two vectors but I do not know how to find the sin(theta).
vector w=i+3j
vector v=<5, 2>
vector w=i+3j
vector v=<5, 2>

A vector is a mathematical object that has both magnitude and direction. It is represented by an arrow pointing in a specific direction and its length represents the magnitude.
The angle between two vectors is the measure of the rotation that is needed to align one vector with the other. It is usually measured in degrees or radians.
To find the angle between two vectors, you can use the dot product formula: cosθ = (a∙b) / (|a|∙|b|), where a and b are the two vectors and θ is the angle between them.
Yes, you can find the angle between two vectors if you only know their components. You can use the same dot product formula, but first you need to find the magnitudes of the vectors using the Pythagorean theorem.
The dot product of two vectors is equal to the product of their magnitudes and the cosine of the angle between them. This means that the dot product can help us find the angle between two vectors.
