An/1-r

Back

Case 4 (no infinity)

Front

1. Set infinity to t. (on the limit that makes the expression 0) 2. differentiate. 3. then subtract.

Case 6

Front

1. Split up the infinities to (upper limit to a non-problem number (that is less than the problem number) and lower limit) and (upper limit and to a non-problem number(that is more than the problem number) ). 2. Set infinity to t. 3. differentiate. 4. then subtract.

Case 3 (negative lower limit and positive upper limit)

Front

1. Split up the infinities to (upper limit 0 and lower limit (negative infinity)) and (upper limit infinity and lower limit 0). 2. Set infinity to t. 3. differentiate. 4. then subtract.

Case 2 (negative infinite lower limit)

Front

1. Set infinity to t. 2. differentiate. 3. plug in the limits. 4. Le'hopitals rule on the t plug. 5. then subtract.
