SUMMARY
The discussion focuses on finding the derivatives of the functions y = x^(ln(x)) and ln(cos⁻¹(x)). The derivative of y = x^(ln(x)) is approached by taking the natural logarithm, leading to ln(y) = ln(x^ln(x)). The derivative of ln(cos⁻¹(x)) is derived using the chain rule, resulting in -x/(cos⁻¹(x)√(1-x²)). The confusion arises from the negative sign in the derivative of arccos(x), which is confirmed as -1/√(1-x²).
