MY NOTES ASK YOUR TEACHER Explain why each of the following integrals is improper. ( a ) Since the function y = x - 7 - has an infinite discontinuity at x = 7, the integral is a Type 1 improper integral. Since the function y = 1 x - 7 has an infinite discontinuity at x = 1, the integral is a Type 2 improper integral. Since the function y = - 1 x - 7 has an infinite discontinuity at x = 7, the integral is a Type 2 improper integral. Since the integral dx X - 7 has an infinite interval of integration, it is a Type 1 improper integral. Since the integral X - has an infinite interval of integration, it is a Type 2 improper integral. ( b ) dx * 2 - 9 Since the function y = has an infinite discontinuity at x = 9, the integral is a Type 1 improper integral. x2 - 9 Since the function y = - 1 x2 - 9 - has an infinite discontinuity at x = 8, the integral is a Type 1 improper integral. Since the function y = x 2 - 9 has an infinite discontinuity at x = 9, the integral is a Type 2 improper integral. Since the integral dx * 2 - g - has an infinite interval of integration, it is a Type 1 improper integral. Since the integral x 2 - 9 has an infinite interval of integration, it is a Type 2 improper integral. ( C ) Jo tan (xX ) dx Since the function y = tan(x) has an infinite discontinuity at x = 0, the integral is a Type 2 improper integral. Since the function y = tan(xx) has an infinite discontinuity at x = -, the integral is a Type 2 improper integral. Since the function y = tan(xx) has an infinite discontinuity at x = 1, the integral is a Type 2 improper integral. Since the integral tan(x) dx has an infinite interval of integration, it is a Type 1 improper integral. Since the integral tan(xx) dx has an infinite interval of integration, it is a Type 2 improper integral. ( d ) ex dx Since the function y = - has an infinite discontinuity at x = 0, the integral is a Type 1 improper integral. Since the function y has an infinite discontinuity at x = -1, the integral is a Type 1 improper integral. Since the function y =- - has an infinite discontinuity at x = 0, the integral is a Type 2 improper integral. Since the integral edx has an infinite interval of integration, it is a Type 1 improper integral. Since the integral dx has an infinite interval of integration, it is a Type 2 improper integral.
