`(1)/(x+6)+(1)/(x+1)=(1)/(x)-(1)/(2x)`

The expression (1)/(1+(x)/(1-(x)/(x+2)))div ((1)/(1-x)+(1)/(1+x))/((1)/(1-x)-(1)/(1+x)) (a) (2x)/(x^(2)+2x+2) (b) (2x)/(x^(2)-1) (c) 1 (d) x^(2)-1

lim_(x rarr0)((1+x)^((1)/(6))-(1-x)^((1)/(6)))/(x)=(1)/(3)

The variance of the random variable X having the following distribution is {:(X=x:,-2,-1,0,1,2),(P(X=x):,(1)/(6),(1)/(6),(1)/(3),(1)/(6),(1)/(6)):}

(x+(1)/(x))(x-(1)/(x))(x^(2)+(1)/(x^(2))-1)(x^(2)+(1)/(x^(2))+1) is equal to x^(6)-(1)/(x^(6))(b)x^(8)-(1)/(x^(8))(c)x^(6)+(1)/(x^(6))(d)x^(8)+(1)/(x^(8))

Add :5x^(2)-(1)/(3)x+(5)/(2),-(1)/(2)x^(2)+(1)/(2)x-(1)/(3) and -2x^(2)+(1)/(5)x-(1)/(6)

(2(x-3))/(x(x-6))<=(1)/(x-1)

int(1)/(x^((1)/(3))+x^((1)/(4)))+(log(1+x^((1)/(6))))/(x^((1)/(3))+x^((1)/(2)))dx=

If A = [(2,1),(0,x)] and A^(-1) = [((1)/(2),(1)/(6)),(0,(1)/(x))] , then the value of x is equal to

(2x-1)/(2x+1)+(2x+1)/(2x-1)=6

Solvef or x,(1)/((x-1)(x-2))+(1)/((x-2)(x-3))+(1)/((x-3)(x-4))=(1)/(6)
