i appreciate any and all help. im gettin further and further into this and im gettin more and more lost...im not very good at writing notation on the computer, but i tried my best...i think most is pretty self explanatory, but sq() means square root...

use the relation lim as x goes to 0...(sinx)/x=1 to establish the limit formulas

3.lim as x goes to 0...tan 2x/sin x =2

4. lim as x goes to 0....(1- cosx)/x^2 =1/2

thanks in advanse for any help, answers, or explanations
