Future Knowledge. Peter Chew Correction For Sine Rule [2nd edition]

In order to have high-quality future education, future Education need to  integrate with technology. But if a knowledge has flaws and not corrected , if we program the uncorrected flaws knowledge to technology such as online calculator, it will cause the online calculator giving some wrong answer. This will not giving a high quality of education. We  have to make sure that our online calculator programming knowledge is free from flaws  or programming `corrected knowledge` in  online calculators. Therefore, future knowledge must free from flaws   or `corrected knowledge` such as Laplace Correction for Newton's Formula1  and Peter Chew Correction for Sine Rule2 .

As Albert Einstein's famous quote  

"We cannot solve our problems with the same thinking we used when we created them".

Using the sine rule to solve some triangle problems will give the wrong answer, which is also the wrong answer given by online calculators using  the  sine  rule. Therefore, corrections need to be created to prevent wrong answers .Peter Chew Correction For Sine Rule gives conditions for preventing wrong answers using the sine rule. The condition is that for an isosceles triangle, if an equilateral opposite angle is given, the given angle must be less than 90°

The Education 4.0 calculator  design includes future knowledge such as Peter Chew Rule, Peter Chew Method, Peter Chew Triangle diagram, and Peter Chew Correction For Sine Rule. Hence, Education 4.0 Calculator provides correct answers to question mentions.

2nd edition adds future knowledge information and adds worksheets with step-by-step answers. .This will increase the understanding of Peter Chew Correction For Sine Rule.
