Could I have help with these two questions about limits and l'hosiptal rule

K Evaluate the following limit. Use I'Hopital's Rule when it is convenient and applicable. 1 - cos 8x lim X - 0 8x How should the given limit be evaluated? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. Use I'Hopital's Rule more than once to rewrite the limit in its final form as lim () X -+ 0 O B. Multiply the expression by a unit fraction to obtain lim ( X -+ 0 O C. Use l'Hopital's Rule exactly once to rewrite the limit as lim ( X -+ 0 O D. Use direct substitution. Evaluate the limit. 1 - cos 8x lim =(Type an exact answer.) x- 0 8x 2Evaluate the following limit. Use I'Hopital's Rule when it is convenient and applicable. e - sin x - 1 lim 4 X-0x + 2x+5x How should the given limit be evaluated? Select the correct choice below and, if necessary, fill in the answer box to complete your choice O A. Multiply the expression by a unit fraction to obtain lim X -+ 0 O B. Use direct substitution. O C. Use I'Hopital's Rule more than once to rewrite the limit in its final form as lim () X-+0 O D. Use l'Hopital's Rule exactly once to rewrite the limit as lim X-0 Evaluate the limit. - sin x - 1 lim (Type an exact answer.) X-0x + 2x +5x
