Explanation:
When we apply Newton’s second law to the box, we set the sum of the x-components of the forces equal to max and the sum of the y-components equal to may.
One of the forces is weight, which equals mg (mass times gravitational acceleration).
The x-component of mg has a sine function, whereas the y-component of mg has a cosine function:
(mg)x = mg sin θ
(mg)y = mg cos θ
