" 7."2x-(1)/(3)=(1)/(5)-x

If quad f=(x)/(1+x^(2))+(1)/(3)((x)/(1+x^(2)))^(3)+(1)/(5)((x)/(1+x^(2)))^(5)+ and g=x-(2)/(3)x^(3)+(1)/(5)x^(5)+(1)/(7)x^(7)-.... then

(4x+1)/(3)+(2x-1)/(2)=6+(3x-7)/(5)

Solve: (2x+1)/(7x-2)=(3)/(5) .

Subtract x^(2)-(5)/(2)x+7 from (1)/(3)x^(2)+(1)/(2)x+2

Solve for : :(3)/(x+1)-(1)/(2)=(2)/(3x-1),x!=(3)/(5),-(1)/(7)

Add: (3x^(2) - (1)/(5)x + (7)/(3)) + ((-1)/(4)x^(2) + (1)/(3)x - (1)/(6)) + (-2x^(2) - (1)/(2)x + 5)

Evaluate: int{(2x-3)^(5)+(1)/((7x-5)^(3))+(1)/(sqrt(5x-4))+(1)/(2-3x)+sqrt(3x+2)}dx
