h c vermas d bst

dat waz quite intrstng

hey dat was outstandng

LETy=f(X) be a function, den d derivative f' (X) is defined by
f(x) =lim f(x+H)-f(x)/h
wer h tends 0
d denominator h represnts d change(increment) in d value of x whenevr it changes frm x to x+h.d numerator represnts d correspondng cnange(increment) in d value of f(x), hence we can write
f(x)= lim increment in f(x)(or y)/increment in x
wer h tends 0
we will use greek leter delta to denote an increment in particular delta x will denote d inerement in x and delta y will denote d incremnt in y. dis notation will give us d derivative of y w.r.t x as d value of
lim delta y/delta x
wer delta x tends 0
hope u gt it

wishing all d goiitians warm n healthy HOLY
