WebOct 27, 2024 · If you are familiar with the properties of dot product and cross product of 2D vectors, it should be obvious that z1 ⋅ z2 = z2 ⋅ z1z1 × z2 = − z2 × z1 so you can proceed to calculate z1 ⋅ z2 = z1 ⋅ z2 + z2 ⋅ z1 2 = ℜ(¯ z1z2) + ℜ(¯ z2z1) 2 = ℜ(¯ z1z2 + ¯ z2z1) 2 = ¯ z1z2 + ¯ z2z1 2 because ¯ z1z2 + ¯ z2z1 is already a real number … WebOct 8, 2015 · 1 Answer. The result of a cross product is a vector, not a float. And anyway, a cross product in 2D doesn't make sense. In 2D the result vector would have to be perpendicular to both a and b and they already define the plane, so the result would have to be in the 3rd dimension.
