    • Fungsi Simetri Terhadap Garis x = a dan Sifat-Sifatnya (Symmetry Function Against the Line x = a and its Properties) 

      UBAIDILLAH, Firdaus (Majalah Ilmiah Matematika dan Statistika Volume 20 Nomor 2 2020, 45 – 52, 2020-09-01)
      An even function is a function with a graph that is symmetric with respect to the y-axis or the line x = 0. In this paper, we will introduce a more general function of the even function, we call it as symmetry function ...

    • Kajian Fraktal i-Fibonacci Word Generalisasi Ganjil dengan Menggunakan L-System (Study on Odd Generalization of i-Fibonacci Word Fractal Using L-System) 

      UMAMI, Riza; PURNOMO, Kosala Dwidja; UBAIDILLAH, Firdaus (Majalah Ilmiah Matematika dan Statistika Volume 19 Nomor 1, 2019, 1 – 8, 2019-03-01)
      The i-Fibonacci Words are words over {0,1}. The i-Fibonacci Word can be associated with a fractal curve by using odd-even drawing rule and L-System methods, then also known as an i-Fibonacci Word fractal. L-System is one ...

    • Kajian Fraktal k-Fibonacci Word Menggunakan Natural Drawing Rule (Fractal k-Fibonacci Word Using Natural Drawing Rule)
