Please see the attachment for the questions.
Please solve each problem step by step giving solutions please. SHOW every step getting to the answer. Show substitutions, etc. DO NOT SKIP STEPS PLEASE! Look below for attachments. Adult student asking for help and I learn by the examples you solve. I learn different than others and please respect the way I learn. Thanks!
If you cannot read the exponents please make an exponent up that may look like the one in the problem. Just tell me you changed the exponent.
Please do problems 1 through 6 (both parts a and b).
Please do Problems 7 -37 odd.
Problems 39 through 47odd
Please see the attached files for the complete solutions.
All these problems involve the principle of writing a given rational expression in partial fractions, in which the degree in numerator is less than that of denominator.
Put x=0 on both sides, which gives, 3A+B=0
Put x=1 on both sides, which gives, 4A+4B=2. Solving both the equations we get, A=-1/4 and B=3/4.
Plugging the values of A and B, we get the integral as
Put x=0 on both sides, which gives, C=1
Put x=-1 on both sides, which gives, A=-1
Put x=1 on both sides, which gives, A+2B+4C=1 that gives on simplification, B=-1
Hence we have 1=-x-x(x+1)+(x+1)2
Write x-1= A(x+1)+Bx(x+1)+Cx2
Put x=0 on both sides, which gives, A=-1
Put x=-1 on both sides, which gives, C=-2
Put x=1 on both sides, which gives, 2A+2B+C=0 that gives on simplification, B=2
Hence we have x-1= -(x+1)+2x(x+1)-2x2
Write x-1= x(Ax+B)+C(x2+1)
Put x=0 on both sides, which gives, C=-1
Put x=1 on both sides, which gives, A+B+2C=0 which ...
Around 25 integrals (definite and indefinite) are evaluated using substitution method, partial fractions method. Some of them need good concept knowledge and skill to compute.
