Evaluate `lim_(xto0) (8)/(x^(8)){1-"cos"(x^(2))/(2)-"cos"(x^(2))/(4)+"cos"(x^(2))/(2)"cos"(x^(2))/(4)}.`

Evaluate `lim_(xto0) (8)/(x^(8)){1-"cos"(x^(2))/(2)-"cos"(x^(2))/(4)+"

1.	Evaluate `lim_(xto0) (8)/(x^(8)){1-"cos"(x^(2))/(2)-"cos"(x^(2))/(4)+"cos"(x^(2))/(2)"cos"(x^(2))/(4)}.`
Answer» Correct Answer - `1//32` `underset(xto0)lim(8(1-"cos"(x^(2))/(4))(1-"cos"(x^(2))/(2)))/(x^(8))` `=underset(xto0)lim(8xx2"sin"^(2)(x^(2))/(8)xx2"sin"^(2)(x^(2))/(4))/(x^(8))` `=underset(xto0)lim(32)/(64xx16).("sin"^(2)(x^(2))/(8))/(x^(4)/(64)).(2"sin"^(2)(x^(2))/(4))/(x^(4)/(16))` `=1/32`
