`1/(6!)+1/(7!)=x/(8!),f i n dx`

1/(6i)+1/(7i)=x/(8i)

if 1/(6!)+1/(7!)=x/(8!) , then x is ……

y=tan^(- 1)sqrt((1-x)/(1+x))f i n d(dy)/(dx)

y=tan^(- 1)sqrt((1-x)/(1+x))f i n d(dy)/(dx)

If y=sin[2t a n^(-1){sqrt((1-x)/(1+x))}],"f i n d"(dy)/(dx)

f'(dx)/((x+6)^(8//7)(x-8)^(6//7)) is equal to

Let f : R to R be continuous function such that f (x) + f (x+1) = 2, for all x in R. If I _(1) int_(0) ^(8) f (x) dx and I _(2) = int _(-1) ^(3) f (x) dx, then the value of I _(2) +2 I _(2) is equal to "________"

If 8f(x)+6f((1)/(x))=x+5 and y=x^(2)(f(x), then (dy)/(dx) at x=-1 is equal to 0( b) (1)/(14)(c)-(1)/(4)(d) None of these
