Your answers to: How would you decide if two vectors are orthogonal?
| use dot product, if ac+bd=0 it is |
| if the scalar product is 0 |
| when they are perpendicular |
| if Ux • Vx + Uy • Vy = 0 |
| when you do Ux times Vx = -Ux times Vy is equal to 0 |
| When they are perpendicular. |
| By using the dot product and seeing if it equals 0 |
| If the components for each of the vectors are opposite and one sign is changed, and if the x’s of the components = the negative of the y’s product. |
| if they are perpendcular |
| I would do the formula ac+bd= |
| You would find if the sum of the x’s added by the sum of the y’s equal to 0. |
| if they are perpendicular, or if Ux*Vx+Uy*Vy=0 |
| By using the dot product and seeing if it equals 0 |
Your answers to When would you use this way to find the dot product?
| wehn you are given either the magnitudes and the angle in between or the two magnitudes and the sot product, or even you can you it to find a magnitude if the angle and dot product is given |
| when you have the magnitudes of the vectors, or when you need to find the angle between two vectors |
| when you have the angle of the vector |
| When you have the components of two vectors. |
| When we have the angle and the magnitudes known. |
| when you are trying to find the angle between the two vectors |
| when we have the magnitude and the angle between the two tails of the vector |
| when they are written in english form
when you have the magnitudes of two vectors and an included angle. |
