Improper Integrals and IMF Flashcards
What are the four ways to solve integral and intermediate problems?
1) L’Hopitals
2) U-Substitution and Factoring
3) Logarithmic Functions
4) Straight Plug In
Where do discontinuities lie?
Lower and upper limits, as well as inside the function
e^ln(y)
y
e^0
1
ln(1)
0
1/0
+infinity
1/infinity
0
Do you KNOW u substitution?
du and how it relates to dx?
Derive u to get du, then make du=u’dx
du/u’=dx
Plug that in for dx
