(x)/(x+1)+(x+1)/(x)=(34)/(15)

Solve: x+(1)/(x)=25(1)/(25)(x-3)(x-4)=(34)/((33)^(2))

(x-1)(x-2)(x-3)(x-4)=15

If A = [[x, -2],[3, 7]] and A^(-1) = [[(7)/(34), (1)/(17)],[(-3)/(34), (2)/(17)]] , then the value of x is

if f(x)=2x+1,1<=x<=2 and f(x)=x^(2)+1,2<=x<=3 then show that int_(1)^(3)f(x)dx=(34)/(3)

Determine the following limit: (lim)_(x->1. 5^(\ ))f(x)= (x + 1.5)(x-1.5)

The series expansion of log[(1 + x)^((1 + x))(1-x)^(1-x)] is (1) 2[(x^(2))/(1.2) + (x^(4))/(3.4)+(x^(6))/(5.6)+...] (2) [(x^(2))/(1.2) + (x^(4))/(3.4)+(x^(6))/(5.6)+...] (3) 2[(x^(2))/(1.2) + (x^(4))/(2.3)+(x^(6))/(3.4)+...] (4) 2[(x^(2))/(1.2) -(x^(4))/(2.3)+(x^(6))/(3.4)-...]

The series expansion of log_(e) [(1 + x^((1 + x))(1-x)^(1-x)] is (1) 2[(x^(2))/(1.2) + (x^(4))/(3.4)+(x^(6))/(5.6)+...] (2) [(x^(2))/(1.2) + (x^(4))/(3.4)+(x^(6))/(5.6)+...] (3) 2[(x^(2))/(1.2) + (x^(4))/(2.3)+(x^(6))/(3.4)+...] (4) 2[(x^(2))/(1.2) -(x^(4))/(2.3)+(x^(6))/(3.4)-...]

Evaluate : lim _(x to 1) (x^(15)-1)/(x^(10)-1)
