The same is true of our current expression: Z x2 −2 √ u du dx dx = Z x2 −2 √ udu. Integration by parts (IBP) can be used to tackle products of functions, but not just any product. functions, differing only by a constant. Since the object initially has speed 0, we again suppose it maintains this speed, but only for a tenth of second; during that time the object would not move. (ii) If one of the function is not directly integrable, then we take it a the first function. 4����?ߐ �*4Gu)Y��9�Z ^A�O�d�o���.��)8��+av�'�����*���X��f#E_�f�qI����Z?g�2X��4}J�l8�d%p* 89 0 obj<>stream 0000087477 00000 n (iv) Any proper rational function f(x) / g(x) can be expressed as the sum of rational functions Chapter 7: Integrals. 0000033839 00000 n However, Bl, B2, B3, PROBLEMS FOR SECTION 9.9 1. 0000003994 00000 n • Put x + 1/x = t or x – 1/x = t as the case may be. 0000010231 00000 n ∫→ Sign of integral 0000016848 00000 n 0000010877 00000 n So we use this: Product of sines sinnx sinkx= 1 2 cos(n−k)x− 1 2 cos(n+k)x. %PDF-1.4 %���� 0000042562 00000 n An example of an area that integration can be used to calculate is the shaded one shown in the diagram. 0000015061 00000 n !�W\q'唋�����nCs�S�S��%�{ʯ5��n{>�ȧ�4Pg��ٱ���@�ʧC�#�F��N�C�Jc5Y0�J�G��׎. %PDF-1.4 0000000016 00000 n 0000090308 00000 n 9�"he���b5.

Chapter 6 Techniques of Integration In this chapter, we expand our repertoire for antiderivatives beyond the “elementary” functions discussed so far. CHAPTER 9 / INTEGRATION The solution procedure for the general linear differential equation (2) is somewhat more complicated, and we refer to FMEA. A review of the table of elementary antiderivatives (found in Chapter 3) will be useful. Case II. !�Z�ϪM�b��������lV=kT function at the point.
