1112) intg{ exp(7x+2) dx } = Aexp(Bx+F)+C. Determine A,B,F. The TI-89 "Approximate" Mode is generally most useful for engineering answers. F is not equal to zero in the HWC answer. Sometimes, another Mode (Exact or Auto) is more useful. ans:3 1114) intg{ 9x ln(x^2) dx } = (Ax^B)*(ln(x^2)+F) + C. Determine A,B,F. ans:3 1130) Evaluate intg_5_13{ (x^2 - 3x + 7) dx }. ans:1 1132) Integrate from 4 to 12 the function: ( 1 / (x^2 + 2x) ). Calculate a floating-point value. ans:1
