Where did they get t=0
V = dx ( first depvabue of displacement wird) dt (a+jb) cos wat + Caj-b) sotot C# what got for & want to denivate this V z dx da Sin Wob + Wo( aj b) falist denied sn. =-wo(atjb) 1 denved cos (* above differentiated Cor and sh terns) Got things sobsitute expression for 8. Again at too Voz W₂ Caj-b) or Caj-b) = Vo So bstitute both into expression for de x = xo cos Wat + V₂ sin wat wo

X = A cas Wok + Aj sin Wob- 2 (a tj b) cos Wok + Caj-b) sin Wot said A ☆ lowest case A and messy, Let's simplify things by setting time too: Xoca tj b CA Look at expression sin term = o (because (6 =0) cos term=1 (just get atjb) So to we also Calculate velocity can (get-I multiply I's together) n
