Question 1 d Calculate — [rı(1). 120] and — [rı(1) Xr2O] first by differentiating the product directly and then by applying the following formulas: dt d - [ri(t) r2(]=r(t) dt d r2 dri + - rz(t) dt dt dr2 dri -+- Xr2(1) dt dt d [rı(t) x r20]=r10) dt ri(t) = = cos ti + sin tj +6tk, r2(t) = 5i + tk Enter the vector i as 7, the vector j as 7, and the vector k as K. d — [ri() r2(0]= Edit dt d [rı(1) xr20)] = ? Edit dt
