The discussion focuses on finding the derivative of the function y = arctan(√(3x² - 1)). The derivative of arctan(x) is established as 1/(1 + x²), but the challenge arises when substituting a more complex expression like √(3x² - 1). The correct approach involves applying the chain rule to differentiate the function, leading to the derivative y' = (3x)/(1 + (3x² - 1)). This method is confirmed through a similar example where y = arctan(x²) is differentiated successfully.
