1. The integral expression [:12 63:4 d3: and the summation expression 4 limaxr>00 E 6:6}:Azck; a = 2, b = 4 k: are equivalent in every way except that... O the limit should be changed to limAwkno. the upper and lower bounds on the summation should be changed from k = 2 and 4 to k: = 1 and n, reSpectively. 0 some change needs to be made, not mentioned above. 0 Both a and I) should be implemented. 0 No change should be implemented; the two expressions are equivalent. 2. The expression limAmHO Elem + 3)2A:ck; a, 2 _3, b 2 2 is equivalent to 1:23 (2:13 + 3)2 dm. 3. The expression limAck-0 E (-2 - sin(Tack)) Axk; a = 0, b =T is equivalent to S" (-2 - sin(wx)) dac.
