Calculus
DifferentiationStep 1 We must decide what to choose for u If u f x then du f x dx and so it is helpful to look for some expression in missing a constant factor We see that 2 3x is part of this integral and the derivative of 2 3x is dx for which the derivative is also present though perhaps 3x dx 20 x 3x 2 2 3x which is simply a constant
