\fliems A region is bounded by the curves y = sinwrr, y = 4z 1, and the x-axis. Determine the area of the region. Use the area formula for a triangle to expedite the calculation and show all your work. Hem 10 For an indefinite integral, use the notation INT in place of the symbol. For example, j (z + 1) dz should be written as INT (z + 1) dz. For a definite integral, use the notation INT (a, b). For example, ff (z + 1) dz should be written } 2 as INT (1,2) (= + 1) dx. For a definite integral that has been integrated, use the notation EVAL (a,b). For example, ('T: + _-:)| should be writien as (\"T' + z) EVAL(1,2).
