**Unformatted text preview: **Z e 1 /x x 3 dx . 2. (10 points) Find Z π/ 2 cos x 2-cos 2 x dx . (Hint: Use the identity sin 2 x + cos 2 x = 1.) 3. (10 points) Find Z 3 x 2 arctan x 3 dx . Note: You may be used to calling the inverse tangent function tan-1 instead of arctan. Both notations are standard. So arctan x 3 means exactly the same as tan-1 ( x 3 ). 4. (10 points) Find Z 2 1 ln x ( x-3) 2 dx . 5. (10 points) Find Z x 3 x 2 + 2 x + 5 dx ....
