(8) Which of the statements is true? (A) limt + COS = = 1 (B) limt + COS = = T (C) limt- COS = 00 (D) limt- cos = does not exist. (9) Graph the appropriate functions (first try by hand and then verify your sketches with the grapher) and then determine the infinite limits. Include small sketches. (a) limx-o+ In x, nbsp;nbsp;nbsp; (b) lime-o+ , nbsp;nbsp;nbsp; (c) lime-o- , nbsp;nbsp;nbsp; (d) lim,-+0 ?, nbsp;nbsp;nbsp; (e) lim,-o+ 2,nbsp;nbsp;nbsp; (f) limx-o- zz, nbsp;nbsp;nbsp; (g) limx-o- cot x, nbsp;nbsp;nbsp; (h) lime-o+ cot x,nbsp;nbsp;nbsp; (i) lime-o cot x.nbsp;nbsp;nbsp; (10) Use algebra and limits laws to find the limits: 2+ 1 (a) limx-70o r-2 (b) limx--00 72-5 It 202+ 1 (c) lim +00 73-2 23 + 1 (d) limx--0o x2+2. Check your answers by graphing the functions
