MoreZitiPlease said:not really..
40cos125=-23
40cos55=23
two diffferent answers
MoreZitiPlease said:so I should use 55? In my textbook it showed 180-55, that's why I used 125. But that example involved a car route or something.
A vector is a mathematical object that represents both magnitude (size) and direction. It is typically denoted by an arrow indicating the direction and length representing the magnitude.
The components of a vector are the perpendicular projections of the vector onto the x, y, and z axes in three-dimensional space. They represent the magnitude of the vector in each direction.
To calculate the components of a vector, you can use trigonometric functions and the Pythagorean theorem. The x-component is found by multiplying the magnitude of the vector by the cosine of the angle it makes with the x-axis. Similarly, the y-component is found by multiplying the magnitude by the sine of the angle. The z-component can be found using the Pythagorean theorem in three-dimensional space.
A vector has both magnitude and direction, while a scalar only has magnitude. Scalars can be thought of as quantities that can be measured by a single number, while vectors require multiple numbers or components to fully describe them.
Vectors are used in many areas of science, including physics, engineering, and biology. They are used to represent forces, velocities, and directions in motion, as well as other quantities such as electric and magnetic fields. Vectors are also used in data analysis and computer science, particularly in machine learning and data visualization.
