You really need to work on your notation here, the first line is missing parentheses or basis vectors for two terms, there is no equality sign between the second line and the third line, the inverse tangent function has no argument and -1/-1 is 1 and not 45.Sall1230 said:A-B =
3-4 i -6--5j
-1i -1j
Tan^-1 = -1/-1 = 45
45+180 = 225
Is this correct?
A vector is a quantity that has both magnitude and direction. It is often represented by an arrow, with the length of the arrow representing the magnitude and the direction of the arrow representing the direction.
The direction of a vector can be determined by using the concept of angles. The angle between the vector and a reference line, such as the x-axis, is known as the direction angle. It is measured in degrees or radians.
The direction of a vector can be represented mathematically using trigonometric functions such as sine, cosine, and tangent. These functions can be used to find the direction angle of a vector.
Yes, a vector can have a negative direction. This simply means that the vector is pointing in the opposite direction of the positive direction, which is usually defined as the direction of the x-axis.
To add or subtract vectors in different directions, you can use the parallelogram law or the head-to-tail method. These methods involve drawing the vectors as arrows, with their tails connected, and using basic geometric principles to determine the resulting vector.
