Since u 2 3x then converting back to an expression in x we get the following Remember to use absolute values where appropriate Inl Injul C

Now if u 2 3x then dx xx du 1 du 2 3x This evaluates as the following Remember to use absolute values where appropriate 11 du

Step 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

Since u 8 x then converting back to an expression in x we get 1 c 28 C

Now if u 8 x4 then This evaluates as x s dx us du 1 us du 8 x4 6 dx

x 18 We must also convert x dx into an expression involving u If u 8 x is substituted into x 8 x4 6 dx then we have We know that du 4x dx and so x dx du x u dx x x3 U6 x dx

Evaluate the integral by making the given substitution x 8 x 6 dx u 8 x x4 6 Part 1 of 4 We know that if u f x then du f x dx Therefore if u 8 x4 then du Orchmit Skin you coppet come back dx
