SUMMARY
In trigonometry, the application of cosα depends on the reference axis from which the angle α is measured. When α is measured from the x-axis, cosα represents the x-component of a vector. Conversely, when α is measured from the y-axis, cosα represents the y-component. This distinction is crucial for accurately resolving vectors in physics and engineering problems.
