Ali, a MAT134 student, writes the following explanation for why the limit lim [x4 - cos(3- ) ] is zero: Since lim z = 0, we conclude, from the limit laws, that I-+0 lim [24 . cos(3 )] - (lim z4 ) - [lim cos ()] - 0 - [jim cos ()] =0. What is wrong with Ali's explanation? How would you correct it? Upload Choose a File
