Knowledge Graph of First Order Ordinary Differential Equations
There are many types of first-order ordinary differential equations with different solutions.In the process of learning,it may be very difficult to learn because of inaccurate judgment of equation types.By constructing knowledge atlas of first-order ordinary differential equations,this paper relates and sorts out complex knowledge,presents the relationship between equation types and solutions of common first-order ordinary differential equations,and illustrates it with examples.Knowledge atlas of differential equations can be constructed to comprehensively and systematically integrate concepts,methods and techniques in differential equations.It not only presents the internal connection and logi-cal relationship between equations,but also cultivates students'logical thinking ability.What's more,it helps students to have a more comprehensive understanding and learning of differential equations,which is conducive to improve students'learning effect.
