Evaluate the integral. (Remember to use absolute values where appropriate. Use C for the constant of integration.) S 7 dx (x-1)(x+6) Write out the form of the partial fraction decomposition of the function (as in this example). Do not determine the numerical values of the coefficients. x - 12 (a) x+x-12 (b) 1 Evaluate the integral. 1 12 1. dx 4x2 + 5X ghi 1 Evaluate the integral. (Remember to use absolute values where appropriate. Use C for the constant of integration.) 1 x(x - a) dx Evaluate the integral. 2 x + x + 1 dx (x + 1)2(x+2) Evaluate the integral. (Use C for the constant of integration.) x+x+1 dx (x + 1) Make a substitution to express the integrand as a rational function and then evaluate the integral. (Use C for the constant of integration.) 9 % dx x + xx Make a substitution to express the integrand as a rational function and then evaluate the integral. (Use C for the constant of integration.) dx + ex Make a substitution to express the integrand as a rational function and then evaluate the integral. (Remember to use absolute values where appropriate. Use C for the constant of integration.) ex dx (ex-4)(e2x + 1)
