Dalam berbagai literatur pada umumnya untuk menentukan koefisien trinomial dengan mudah dapat ditentukan dengan menggunakan konsep kombinasi dan koefisien binomial, hal ini disebabkan karena koefisien trinomial sangat erat hubungannya dengan koefisien binomial dan konsep kombinasi. Untuk konstruksi koefisien trinomial biasanya dikonstruksi pada limas Pascal yang asalnya adalah dari segitiga Pascal. Pada tulisan ini akan diberikan alternatif menentukan koefisien trinomial dan alternatif konstruksinya. Alternatif yang diberikan adalah dengan modifikasi perkalian bersusun. Modifikasi perkalian bersusun yang dimaksud adalah dengan hanya menuliskan bagian proses perkalian bersusun pada bentuk trinomial, kemudian menyisipkan nol diantara koefisien-koefisien trinomial pada bagian proses perkalian bersusun trinomial pangkat . Selanjutnya alternatif konstruksi koefisien trinomial dikonstruksi pada kerucut.
