A sequence is defined as: U(n+1) = 1/U(n) where U(1)=2/3. Find the sum from r=(1-100) for U(r)

U n+1 =1/U n where U 1 = 2/3First of all, we need to find U 2 and U 3 and so on, up until we notice a pattern in the answers. U 2 = 1/(2/3) = 3/2U 3 = 1/(3/2) = 2/3As we can see, U 1 and U 3 are equal, and s...

Find the indefinite integral of f(x)=(1-x^2)/(1+x^2)

Int() in this case will refer to integralsAnswer is: f(x)=(1-x^2)/(1+x^2)=(2-(1+x^2)/(1+x^2)=-1+2/(1+x^2)=> Int(f(x))=Int(-1+2/(1+x^2))=Int(-1)+2Int(1/(1+x^2))=-x+2tan^-1(x)+C
