Description
The Fourth industrial revolution like the developments of robots, AI and automation seem inevitable and technical tools have had a major impact on advanced mathematics teaching and mathematics learning. Educator and researcher must think to create a new Technical tools to help mathematics teaching and mathematics learning for the needs of the AI age. Today's online calculators and math applications, photo math applications and calculators contain only the knowledge already stated in the book such as the sine and cosine rule. However, some areas of mathematics today are not complete, which leads to a certain field where some of the same questions are difficult to solve or cannot be solved. As example, We realize that Math Portal is able to tackle problems that can be solved directly by sine rule or cosine rule. But when given problem with 2 sides and an included angle, if we use Math Portal to find other non-included angle, Math Portal will show error.
