- What are direction ratios and direction cosines?
- What is triangle law and parallelogram law of vector addition?
- Write dot product and cross product of two vectors.
Intext Question:
- Write the direction cosines of line joining points P(x1, y1, z1) and Q(x2, y2, z2).
- Write the cartesian equation of line passing through two points P(x1, y1, z1) and Q(x2, y2, z2).
- Write the equation of plane which is distance d from origin and the direction cosines of the normal to the plane are l, m and n
