Question in Limits
Just what the title says, I guess. I couldn't find a 0^0 that didn't converge to 1 except things like x^(1/ln(x)) as x->0, but they just need the e^ln() transformation, not L'hopital's rule!

Question in Sequences and Series
Test whether a student knows the root test of a series, and how to use it. Series include those that the root test is inconclusive for. This question could be better in that it could go through the working of determining the limit but I hope to make a separate question which deals with that.

Question in Sequences and Series
Basic question on limit laws and the squeeze theorem for sequences.
-
Question in Sequences and Series
Determine a finite sum and a limiting sum of a geometric series written using sigma notation. I'm not sure how to eliminate rounding errors...
-
Question in Sequences and Series
Often students need practice re-indexing series, these are three questions that give them that opportunity.

Question in Sequences and Series
Test whether a student knows the divergence test of a series, and how to use it. Series include those that the diverence test is inconclusive for. This question could be better in that it could go through the working of determining the limit but I hope to make a separate question which deals with that.

Question in Sequences and Series
This question tests to see if students can recognise a $p$-series and based on its $p$-value determine if it is convergent or divergent.
-
Question in Sequences and Series
This question tests to see if students can recognise a geometric series and based on its common ratio determine if it is convergent or divergent.
-
Question in Sequences and Series
This question tests to see if students can recognise an alternating series and based on the alternating series test and the divergence test determine if it is convergent or divergent.
At the moment there is no example included with $b_n\rightarrow 0$ which isn't eventually monotonically convergent.

Question in Sequences and Series
Test whether a student knows the ratio test of a series, and how to use it. Series include those that the ratio test is inconclusive for. This question could be better in that it could go through the working of determining the limit but I hope to make a separate question which deals with that.
