Question 2
Question
\[\int x ln(x) dx = \]
Answer
-
\[\int e^x g(x) dx - \int e^x g'(x) dx \]
-
\[e^x g(x) - \int e^x g'(x) dx \]
-
\[e^x g(x) + \int e^x g(x) dx \]
-
\[\int e^x g(x) dx + \int e^x g'(x) dx \]
Question 3
Question
\[\int x sin(x) dx = \]
Answer
-
\[sinx - cos(x) \]
-
\[sinx+ x cos(x) \]
-
\[cosx - x sin(x) \]
-
\[sinx - x cos(x) \]
Question 4
Question
\[\int \frac {x^2}{e^x} dx = \]
Answer
-
\[x (lnx + 1) \]
-
\[x (lnx - 1) \]
-
\[x lnx - 1 \] \]
-
\[\ (lnx -x) \] \]
