3.3. EFFECT OF PRESSURE ON MOMENTUM TRANSPORT 41(a) Bessel equation:Solution:x 2 d2 ydx 2 + xdy dx + (x2 − n 2 )y = 0y = A 1 J n (x) + A 2 Y n (x)where J n (x) is bounded for x → 0, and Y n (x) is bounded forx → ∞. tem Modified Bessel equation:Solution:x 2 d2 ydx 2 + xdy dx − (x2 + n 2 )y = 0y = A 1 I n (x) + A 2 K n (x)where I n (x) is bounded for x → 0, and K n (x) is bounded forx → ∞.
