Use u-substitution to determine the approximate value of e te z For an indefinite integral, use the notation INT in place of the symbol. For example, f (x + 1) dx should be written as INT (x + 1) dx. For a definite integral, use the notation INT (a, b). For example, (x + 1) dx should be written as INT (1, 2) (x + 1) d. For a definite integral that has been integrated, use the notation EVAL (a, b). For example, ( (+2) EVAL (1, 2). 2 + x) - x) | dx. Show all work. should be written as
