But how exactly i can evaluate the integral and get the result given by: I = \frac{R^2}{\alpha_m^2 - \alpha_n^2}[\alpha_mJ_0(\alpha_n)J_1(\alpha_m) - \alpha_nJ_0(\alpha_m)J_1(\alpha_n)] or another more general formula for Bessel functions of different order?

When finding the coefficients of a Fourier-Bessel series, the Bessel functions satisfies, for k_1and k_2 both zeroes of J_n(t), the orthogonality relation given by: $$\int_0^1 J_n(k_1r)J_n(k_2r)rdr = 0, (k_1≠k_2)$$ and for k_1 = k_2 = k: $$\int_0^1 J_n^2(kr)rdr = \frac12J_n^{'2}(k)$$ I...
