The space derivatives of the order integers are approximated depending on the shifted Legendre polynomials. The numerical tests suggest for two examples that the proposed approach are efficient and robust in its solutions for the time-fractional bioheat equation. Furthermore, some the preliminaries and definitions of the fractional derivatives, theorems and lemmas related to the fractional shifted Legendre polynomials are inserted to verify the convergence results of the algorithm under consideration. Finally, we discussed the error analysis.
