If `3x+2y=1` is a tangent to `y=f(x)` at `x=1//2`, then `lim_(x to 0)(x(x-1))/(f((e^(2x))/(2))-f((e^(-2x))/(2)))`

If 3x+2y=1 is a tangent to y=f(x) at x=1//2 , then lim_(xrarr0) (x(x-1))/(f((e^(2x))/(2))-f((e^(-2x))/(2)))

If 3x+2y=1 is a tangent to y=f(x) at x=1//2 , then lim_(xrarr0) (x(x-1))/(f((e^(2x))/(2))-f((e^(-2x))/(2)))

If 3x+2y=1 acts as a tangent y=f(x)atx=(1)/(2) and if p=lim_(x rarr0)(x(x-1))/(f((e^(2x))/(2))-f((e^(-2x))/(2))) then sum_(r=1)^(oo)p^(r)=......... (A) (1)/(2)(B)(1)/(3)(C)(1)/(6)(D)(1)/(7)

f(x)=(e^(2x)-1)/(e^(2x)+1) is

f(x)=((e^(2x)-1)/(e^(2x)+1)) is

f(x) = ((e^(2x)-1)/(e^(2x)+1)) is

If the normal to y=f(x) at (0, 0) is given by y-x =0, then lim_(x to 0)(x^(2))/(f(x^(2))-20f(9x^(2))+2f(99x^(2))) , is

If the normal to y=f(x) at (0, 0) is given by y-x =0, then lim_(x to 0)(x^(2))/(f(x^(2))-20f(9x^(2))+2f(99x^(2))) , is

If the normal to y=f(x) at (0, 0) is given by y-x =0, then lim_(x to 0)(x^(2))/(f(x^(2))-20f(9x^(2))+2f(99x^(2))) , is
