So,the 'y' in the question,arcsin(2x/1x^2) is a little difficult to handle,so a smart substitution has been done in the form of x=tan θ which simplifies the 'y' to be equal to 2 arctan(x) Now,y=2tan^1(x) Differentiating both sides,we get dy/dx=2*1/1x^2 as derivative of tan^1(x) is 1/1x^2 And dy/dx is what was asked in the question Cheers ) 133K views View upvotes 9 2 Related Ex 75, 6 Integrate the function (1 − 𝑥2)/(𝑥(1 − 2𝑥)) ∫1 (1 − 𝑥2)/(𝑥(1 − 2𝑥)) 𝑑𝑥= ∫1 (1 − 𝑥^2)/(𝑥 − 2𝑥^2 ) 𝑑𝑥Factor x^{2}2x1 In general, when x^{2}bxc is a perfect square, it can always be factored as \left(x\frac{b}{2}\right)^{2} \sqrt{\left(x1\right)^{2}}=\sqrt{2} Take the square root of both sides of the equation x1=\sqrt{2} x1=\sqrt{2} Simplify x=\sqrt{2}1 x=\sqrt{2}1 Subtract 1 from both sides of the equation x ^ 2 2x 1 = 0 Quadratic equations such as this one can be solved
