Don vectors ch cross product mhanje sadh multiplicationch aahe ka? Samja, A ani B he don vectors aahet. Tyanna eka saman suruvatichya bindupasun kadhla, tar te ek parallelogram tayar kartat. Tyach kshetrafal apan nehmi pramane aadhar gunile unchi asan pahato. A x B chya parimanach sutra aahe: AB sin theta. Hech tya parallelogram ch kshetrafal. Pan thamba: parinam fakta ek sankhya nahi. To ek nava vector aahe, jo A ani B ne banavlelya talala perpendicular asto. Tyachi yogya disha right-hand rule ne tharava. Kram badlala, tar disha ulatte - A x B = -(B x A). Mhanun he sadh multiplication nahi. Donhi vectors parallel astil, tar theta shunya kiwa 180 ansh, sin theta shunya, ani cross product zero. Te perpendicular astil, tar sin theta ek; mhanun pariman maximum. Mhanun uttar: cross product don vectors ch parallelogram kshetrafal ani tya talala perpendicular disha aslela vector deto.
