(4)-teng1ikka tayanib asosiy elementar funksiyalarning differensiali va differensiallash qoidalarini kelitiramiz:
1. d(c)——0
3. d(a )-- a‘£nadx, d( )—— dx
2. d(x )= -a
d(I'og x) ——
x ‹b:
‹f(sins)= cess dr
9. d(arcsia x)= 1
11. d(arctg x) -—
6. d(cost)= —sin z dr
10. d(arccos x)= — gg dr
Differensiallash qoidalari
1. d(cf(x)) —— c - df(x c —- const 2. df(x)k gfx)] —— df(x)k dg(x)
Yuqori tartibli differensiallar
df( )—- f’(x tenglikda dx erkli o‘zgaruvchining orttirmasini o‘zgarmas deb qarasak, df(x) funksiya differensiali x ning funksiyasi
