We just found this out when we stumbled upon Mel’s thesis, entitled “A proposed workbook in trigonometry for high school students”, in the online database of the National Library (click image to enlarge).
As we all know, Mel moved with his family to Sta. Rita, where he would eventually teach mathematics at Guagua National Colleges’ engineering department.
We haven’t heard from Mel since he immigrated to the US several years ago, but wait for further announcement about him next month. We have requested a friend to look for his relatives in Pampanga.
