I'm sorry, but this material is so far past "Beginning Algebra" that I'm afraid there is no possible way to explain this to you in just a forum posting. You need to finish your current algebra course, take a few more, take trigonometry, and then take a course or two of calculus. By that point, this can be explained.carlasader said:i have attached my math project because i need help in solving it and i dont know where to start from
3-a) Find int [1,illegible] [ (1 + x^2) / x ] dx.
3-b) Express f(x) = (3 + x) / [ (1 - x)(1 + 3x) ] in partial fractions.
3-c) Hence, find int [0, illegible] [ f(x) ] dx.
Given: f(x) = (x + 4) / [ (x + 1)[sup:2ew98azy]2[/sup:2ew98azy] (x + 2) ].
4-a) Express f(x) as A / (x + 1)[sup:2ew98azy]2[/sup:2ew98azy] + B / (x + 1) + C / (x + 2), and find the values of A, B, and C.
4-b) Evaluate f'(1), giving your answer as an exact rational number.
The finite region R is bounded by the curve y = f(x), the coordinate axes, and the line x = 3.
4-c) Find the area of R, giving your answer in the form "p + ln(q)", and find the values of p and q.
Okay, but now you need to explain partial-fraction decomposition and integration to this elementary-algebra student.markbrock30 said:...integrate (1/x = In(x))
( px + q ) / ( (ax + b)(cx + d) ) = A / (ax + b) + B / (cx + d)
...Integrate that answer.
