Hello Student,
Please find answer to your question below

I = \int_{0}^{1}tan^{-1}(1-x+x^2)dx
I = \int_{0}^{1}cot^{-1}(\frac{1}{1-x+x^2})dx
I = \int_{0}^{1}cot^{-1}(\frac{1}{1-x(1-x)})dx
I = \int_{0}^{1}(\frac{\pi }{2}-tan^{-1}(\frac{1}{1-x(1-x)}))dx
I = \int_{0}^{1}(\frac{\pi }{2}-(tan^{-1}x-tan^{-1}(1-x))dx
I = \int_{0}^{1}\frac{\pi }{2}dx-\int_{0}^{1}tan^{-1}xdx+\int_{0}^{1}tan^{-1}(1-x)dx
I = \int_{0}^{1}\frac{\pi }{2}dx-\int_{0}^{1}tan^{-1}xdx+\int_{0}^{1}tan^{-1}(1-(1-x))dx
I = \int_{0}^{1}\frac{\pi }{2}dx-\int_{0}^{1}tan^{-1}xdx+\int_{0}^{1}tan^{-1}xdx
I = \frac{\pi }{2}
