**Reiny**, Monday, September 19, 2011 at 4:45pm∫(6x^2 + 12x^(3/2) +4x+9]/√x)

= ∫ 6x^(3/2) + 12x + 4x^(1/2) + 9x^(-1/2) dx

= (12/5)x^(5/2) = 6x^2 + (8/3)x^(3/2) + 18x^(1/2) + c

∫ (12sinx + 4tanx) dx

= ∫( 12sinx + 4 sinx/cosx) dx

= -12cosx - 4ln(cosx) + c

∫ (x^7) e^(x^8) dx

= (1/8) e^(x^8) + c
