should we divied it , I mean solve it like x = 1/2at^2 ,x= bt^3 and take each part individual ! how can get red of (sin) from this formula , also here should i handle it individual !

if at^2 is distance, then a must be distance/time^2 okay but from where can i get distance ?! i mean as a number ! also here sin (C2 t) i think it is constant so we can't take dimension or i am wrong :( Again Thank u a lot :D
