Suppose a vector makes an angle with respect to the y-axis. What could be the x and y components of vector ?
The x and y components of vector are and , respectively.
A vector can be divided into two or three components depending upon the coordinate axes. The vector can be split into two or three scalar forms of quantities.
The components of the vector can be generally obtained when the vector is inclined at some angle with any of the coordinate’s axes.
The resultant of two or more vectors can be calculated with the help of the addition or the subtraction of the horizontal and vertical components of the individual vectors.
Consider that the Cartesian coordinates system consists of x and y-axes. Vector is making an angle of with the y-axis. Then, vector is broken into two components along the x and y-axes.
While resolving any of the vectors, it can be noted that the axis with which the vector is inclined is considered the (cosine) component of the same vector. The other axis could be considered the (sine) component of the same vector.
It is given that vector is inclined with the y-axis. So, the y-axis consists of the (cosine) component, and therefore, the other axis, that is, the x-axis, can be taken as the (sine) component of vector.
The x-component of vector can be expressed as
Here, is the x-component of the , is the angle of inclination of the vector with the y-axis, and V is the magnitude of the vector.
The y-component of vector can be expressed as
Here, is the y-component of the vector , and is the angle of inclination of the vector with the y-axis.
Thus, the x and y components of vector are and , respectively.
