Ada yang bisa jawab gak... mohon bantuannya lagi butuh banget :)
GhinashodaY = L i m (1 - √cosx)(1+√cosx) x⇒0 x² ( 1 + √cosx ) = L i m (1 - Cosx) x⇒0 x²(1+√cosx) = L i m 2Sin²(1/2)x(1/2 x)² x⇒0 x²(1+√cosx)(1/2 x)² = L i m Sin²1/2 x 2(1/2 x)² x⇒0 (1/2 x)² x²(1+√cosx) = L i m 1/2 x² x⇒0 x²(1+√cosx) = 1/2 1 + √cos0 = 1/2 1 + 1 = (1/2)/2 = 1/4
x⇒0 x² ( 1 + √cosx )
= L i m (1 - Cosx)
x⇒0 x²(1+√cosx)
= L i m 2Sin²(1/2)x(1/2 x)²
x⇒0 x²(1+√cosx)(1/2 x)²
= L i m Sin²1/2 x 2(1/2 x)²
x⇒0 (1/2 x)² x²(1+√cosx)
= L i m 1/2 x²
x⇒0 x²(1+√cosx)
= 1/2
1 + √cos0
= 1/2
1 + 1
= (1/2)/2
= 1/4
