2. The integral expression 0 far/2 sec2 (3) dm and the summation expression limmwo ZU:7r/2 sec2(mk)Aack; a : 71'/2, b 2 0 are equivalent in every way except that... O the limit should be changed to limAxkmo- O the upper and lower bounds on the summation should be changed from \" k = 7r/ 2 \" and \" 0 \" 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 Niether (I. nor 1) should be implemented; the two expressions are equivalent
