Problem solving is one-skills most importantly no could separated adri learning math. In the process of problems, students will not be from their positive attitude towards mathematics (mathematical disposition). On other hand, results tests and observations during pandemic show that mathematical problem-solving ability class X Gondang Vocational School relatively low. Moment solve-problem math,...

‎Mathematical models are the most important tools in epidemiology to understand previous outbreaks of diseases and to better understand the dynamics of how infections spread through populations‎. ‎Many existing models closely approximate historical disease patterns‎. ‎This article investigates the mathematical model of the deadly disease with severe and uncontrollable bleeding‎, ‎Ebola which is...

In this paper, we have analyzed a mathematical model for the study of interaction between tumor cells and oncolytic viruses. The model is analyzed using stability theory of differential equations. We gain some conditions for global stability of trivial and interior equilibrium point.
