Let `Veca = Hati + 4hatj + 2hatk, Vecb = 3hati - 2hatj + 7hatk ` and `Vecc = 2hati - Hatj + 4hatk`. Find a Vector `Vecd` Which is Perpendicular to Both `Veca` and `Vecb`, and `Vecc.Vecd = 15`. - Mathematics
Let `veca = hati + 4hatj + 2hatk, vecb = 3hati - 2hatj + 7hatk ` and `vecc = 2hati - hatj + 4hatk`. Find a vector `vecd` which is perpendicular to both `veca` and `vecb`, and `vecc.vecd = 15`.
