Timeline for In NDSolve, how to involve in the odes a integration function that depends on ode functions and can't be analytically integrated?

@rewi, for example, if the integrand in my code is Sin[y1[t] y2[t] + Cos[r]]/(Cos[r] + 2), then your code would fail.

@rewi thanks, but this not what I want, because if you meet a more complicated integrand, Integrate would run "forever", so your code would fail (I have tested this by changing the integrand). NIntegrate is a must for me.
