COMMENT
|
Serial solution of ode (A.Gruzinov,2005): cos[t]f'[t]+sin[t]f''[t]+3/4 sin[t]f[t]=0, f[ -pi/2]=1, f'[ -pi/2]=0, f[t]=1-3/8(t+pi/2)^2-5/128(t+pi/2)^4-193/15360(t+pi/2)^4-... All coefficients (except 1) are negative, there is no simple recursion or other formula for the serial coefficients.
