Use u-substitution to determine the approximate value of Jo zte z e-ez de. Show all work. For an indefinite integral, use the notation INT in place of the symbol. For example, J (x + 1) da should be written as INT (x + 1) dc. For a definite integral, use the notation INT (a, b). For example, S (x + 1) dx should be written as INT (1, 2) ( + 1) dc. For a definite integral that has been integrated, use the notation EVAL (a, b). For example, 2 should be written as 2 + 2 ) EVAL (1, 2)
