## anonymous 4 years ago Vectors if a= i+2k and b= -j+k determine a x b,

Assuming this is a cross-product of these two vectors we need the determinant of the following matrix|dw:1327355060225:dw|that determinant will be our new vector v such that$\overrightarrow{v}=\overrightarrow{a}\times\overrightarrow{b}$
