"mixed derivatives" is a correct and usable phrase in written English.
It is used to refer to a combination of financial instruments that contain elements of both equity and debt, and can be used as an alternative investment for those seeking more security than the stock market alone can provide. For example, "The fund invests primarily in mixed derivatives, allowing investors to benefit from both the returns of the stock market and the security of debt instruments".
In [26], Luo studied the following singular -point dynamic eigenvalue problem with mixed derivatives: (1.4).
This was due to mixed derivatives appearing in the formulation of free edge boundary conditions.
The schemes include a new approximation for mixed derivatives and accurate treatment of internal separatrix layers.
Recently, Torres [5] showed the existence of a solution for the fractional p-Laplacian Dirichlet problem with mixed derivatives.
Overdetermination preserves ellipticity, while first-order systems eliminate mixed derivatives, resolve convection diffusion conflicts, and simplify derivative computations.
Mixed derivatives were then analyzed by high performance liquid chromatography coupled to positive electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS).
The method is based on approximating a sixth-order mixed derivative by a series of Haar wavelet basis functions.
The quanto option pricing model is an important financial derivatives pricing model; it is a two-dimensional Black-Scholes (B-S) equation with a mixed derivative term.
Lee et al. [23] developed a CCD method for directly solving the general two-dimensional (2D) linear partial differential equation with a mixed derivative.
The bright one- and two-soliton solutions of the coupled mixed derivative nonlinear Schrödinger equations in birefringent optical fibers are obtained by using the Hirota's bilinear method.
The pulse propagation in the picosecond or femtosecond regime of the birefringent optical fibers is governed by the coupled mixed derivative nonlinear Schrödinger equations.
