Once the substitution was made the resulting integral became Z √ udu. MATH 105 921 Solutions to Integration Exercises Therefore, Z sintcos(2t)dt= 2 3 cos3 t+ cost+ C 7) Z x+ 1 4 + x2 dx Solution: Observe that we may split the integral as follows: Z x+ 1 4 + x 2 dx= Z x 4 + x2 dx+ Z 1 4 + x dx On the rst integral on the right hand side, we use direct substitution with u= 4+x2, and du= 2xdx. Your instructor might use some of these in class. To perform the integration we used the substitution u = 1 + x2. 3�"[[0�T�!8�|��d�>�:ijZG����4��K3��.�!�*V��u8J���JP=� 5���G����I��J�%ڢ�uە���W>�PH�R(�]���\�'�� �j�r�G� 4��@�z��妯u��@�S��:�\;CBO���I5*4 ���x��ʔ{&[ʭjE�ְ��ԡ,?�r.��q�tS 59�"����,���=���.

Choosing the correct substitution often requires experience. This skill develops with practice. Here du/dx denotes the derivative of the function u = u(x); dx is the symbol that is Calculus Integration by Parts Worksheets. R sinx (cosx)5 dx 8. Z sin10(x)cos(x) dx (a)Let u= sin(x) dx (b)Then du= cos(x) dx (c)Now substitute Z sin10(x)cos(x) dx = Z u10du = 1 11 u11+C = 1 11 sin11(x)+C 7.
