ThenIm,n=m−1m+nIm−2,nI_{m,n}=\frac{m-1}{m+n} I_{m-2,n}Im,n=m+nm−1Im−2,nif m≥2m\ge 2m≥2 andIm,n=n−1m+nIm,n−2I_{m,n}=\frac{n-1}{m+n} I_{m,n-2}Im,n=m+nn−1Im,n−2if n≥2n\ge 2n≥2.The case m=0m=0m=0 recovers the sine-power recurrence; the case n=0n=0n=0 recovers the cosine-power recurrence. The base values needed to stop the reduction are I0,0=π2I_{0,0}=\frac{\pi}{2}I0,0=2π, I0,1=1I_{0,1}=1I0,1=1, I1,0=1I_{1,0}=1I1,0=1 and I1,1=12I_{1,1}=\frac{1}{2}I1,1=21.[1]:Reduction formula[2]:Proof[3]:∫0π/2cos5xsin4x dx\int_0^{\pi/2}\cos^5 x\sin^4 x \, dx∫0π/2cos5xsin4xdx[RIGHT CLICK][ASK AI]
