Diophantine - Equation Ppt

Let m>n>0 be coprime and of opposite parity. Then: x = m^2 - n^2, y = 2mn, z = m^2 + n^2 All primitive integer solutions (up to order and signs) come from such m,n.

  • Step 2: Check: ( 4 \mid 1000 ) → Yes.
  • Step 3: Back-substitute to find ( x_0 = 500, y_0 = -4250 )
  • Step 4: General: ( x = 500 + 5t, y = -4250 - 43t )

  • Click reveals: (a) yes (gcd=5 divides 15), (b) no (gcd=7 does not divide 8), (c) no (gcd=3 does not divide 4).
  • The first three slides of your Diophantine equation PPT must establish the foundation. Do not rush into complex solving methods. Instead, build curiosity.

  • NOT Diophantine (Real numbers):

  • Find integer right triangles with legs 3 and 4.
    Given (x=3, y=4) → (3^2 + 4^2 = 9+16=25) → (z=5) (a known triple).

    General formula: Let (m>n), coprime, opposite parity:
    (m=2,n=1) → (x=3, y=4, z=5) ✓


    This sequence (slides 4–6) is the mechanical heart of any Diophantine equation PPT. Ensure plenty of practice problems with answers on subsequent slides.
