(A) Given the equation: $\int\limits_0^x {f\left( t ight)} dt = {x^2} + \int\limits_x^1 {{t^2}f\left( t ight)dt}$.Differentiating both sides with respect to $x$ using the Leibniz integral rule:$\frac{d}{dx} \int\limits_0^x {f\left( t ight)} dt = \frac{d}{dx} ({x^2}) + \frac{d}{dx} \int\limits_x^1 {{t^2}f\left( t ight)dt}$.$f(x) = 2x - x^2 f(x)$.Rearranging the terms to solve for $f(x)$:$f(x) + x^2 f(x) = 2x$.$f(x)(1 + x^2) = 2x$.$f(x) = \frac{2x}{1 + x^2}$.Now,find the derivative $f'(x)$ using the quotient rule:$f'(x) = \frac{(1 + x^2)(2) - (2x)(2x)}{(1 + x^2)^2} = \frac{2 + 2x^2 - 4x^2}{(1 + x^2)^2} = \frac{2(1 - x^2)}{(1 + x^2)^2}$.Substitute $x = 1/2$:$f'(1/2) = \frac{2(1 - (1/2)^2)}{(1 + (1/2)^2)^2} = \frac{2(1 - 1/4)}{(1 + 1/4)^2} = \frac{2(3/4)}{(5/4)^2} = \frac{3/2}{25/16} = \frac{3}{2} 	imes \frac{16}{25} = \frac{24}{25}$.

If $\int\limits_0^x {f\left( t \right)} dt = {x^2} + \int\limits_x^1 {{t^2}f\left( t \right)dt} $,then $f'(1/2)$ is
