- The unknown displacement field is approximated by discontinuous, piecewisely differentiable functions.
- Let be continuous on the interval, then there exists differentiable function on, such that for any in,. In words, the continuous functions must have antiderivatives.
- The approximation of differentiable functions by a kind of interpolatory rational functions is discussed,and the corresponding order of approximation is obtained.
- In this paper, we extend the theorem on generalized quasi-analyticity of the infinitely differentiable functions in the closed angular domain to the functions of several complex variables.
- The uniqueness theorem of generalized quasi-analyticity of the infinitely differentiable functions in some closed angular domain is extehded to the functions of several complex variables.
- For functions of them ,the delta method implies the following result, proved in Section 14.1.4:Let denote a differentiable function of , with sample value for a multinomial sample.
