As we head into something new, this handout of Algebraic Limit Rules is handy (which was given to us on Friday)
Limits and Functions
Suppose that limits
exist and let "c" be a constant
CMR (Constant multiple rule)
The limit of a constant times a function is the constant times the limit of the function
lim c f(x) = c lim f(x)
SR (Sum of Function Rule)
The limit of a sum is the sum of the limit
lim (f(x)+g(x)) = lim f(x) + lim g(x)
DR (Difference of Function Rule)
The limit of a difference is the difference of the limits
lim (f(x) - g(x)) - lim f(x) - lim g(x)
PR & QR (Product of Function and Quotient of Functions Rule)
PR: lim (f(x)g(x)) = (lim f(x))(lim g(x)) QR: lim (f(x)/g(x)) = lim f(x)/lim g(x)
Example 1:
Example 2:
Example 3:
Note:
The limits are the same but the function itself is different, for
f(x) = (x2/x-1 - 1/x-1) there is a discontinuity at x = 1
For more examples similar to these one look at example 2 and 4 in the Algebraic Limit Rules booklet.
Example 2
Example 4
Homework: Exercise 2.7
1-9 (odd)
14-27 (odd)
and 24
And now it is time for the ROFL corner!
Since the last riddle was a tad difficult, I'll give you guys an easier one, which means that you won't need a hint for this one. ;D
How many times can you take 5 out of 25?
And if that one is too easy try this one! (Sorry!! I don't have a hint for this one!)
What belongs to you, but is mostly used by others?
Have fun!
Finally the next scribe will be...... Hi I'm Justice!
