The area of the first quadrant bounded by the y-axis, the line y=4-x, and the graph of y=x-cosx is approximately 3.41. This is because we can use the integration method to find the area. First, we need to set up the integral as follows: A = ∫ (4-x) - (x-cosx) dx The integral can be evaluated by parts, and the result is equal to 3.41.
