Cara nya gimana yah?

a. Lim x=> 0 (-g(x)) = ?

= – Lim x=> 0 g(x)   <= <= lim x=> 0 g(x) = √2

= -√2

b. Lim x=> 0 (g(x).f(x)) = ?

= Lim x=> 0 g(x) . Lim x=>0 f(x)

= √2 . 1/2

= 1/2 . √2

c. Lim x=> 0 (f(x)+g(x)) = ?

= Lim x=> 0 f(x) + Lim x=> 0 g(x)

= 1/2 + √2

= 1/2 + 2√2/2

= (1+2√2)/2

d. Lim x=> 0 1/f(x) = ?

= (Lim x=> 0 (1)) / (Lim x=> 0 f(x))  <= Limit konstanta ya cuma konstanta itu sendiri

= 1/(1/2)

= 2

e. Lim x=> 0 (x+f(x)) = ?

= Lim x=> 0 (x)  + Lim x=> 0 f(x)

= 0 + 1/2

= 1/2

f. Lim x=> 0 (f(x).cos x/(x-1)) = ?

= (Lim x => 0 f(x) . Lim x=> 0 cos x) / (Lim x=> 0 (x-1))

= (1/2 . cos 0)/(0-1) <= cos 0 = 1

= (1/2.1)/1

= 1/2
