The results are. d dx (sinx) = cosx and d … WebNo, because cos⁻¹ x is NOT the same as (cos x)⁻¹. Therefore, arccos x is NOT 1/cos x. To be precise, arccos x = 𝑖 ln [ x - 𝑖√(1-x²) ] The ⁻¹ beside the name of a function refers to the inverse function, not the reciprocal. So, this notion is NOT an exponent. This inconsistency in notation often causes confusion with students.
