Oblique explicit wave solutions of the fractional biological population (BP) and equal width (EW) models

This research uses the extended exp-$( -\varphi(\vartheta ) ) $ ( − φ ( ϑ ) ) -expansion and the Jacobi elliptical function methods to obtain a fashionable explicit format for solutions to the fragmented biological population and the same width models that depict popular logistics because of deaths or births. In mathematical terminology, the linear, hyperbolic, and trigonometric equation solutions that have been found describe several innovative aspects from the two models. Sketching these solutions in different types is used to give them more details. The accuracy and performance of the method adopted show their ability to be applied to various nonlinear developmental equations.
