- How to solve vector algebra problems

When you need to add or substract two or more vectors, you can use following procedure

- Select a coordinate system that is convenient. (Try to reduce the number of components you need to find by choosing axes that line up with as many vectors as possible.)
- Draw a labeled sketch of the vectors described in the problem.
- Find the x and y components of all vectors
- Compute the resultants in x and y direction
- If necessary, use the Pythagorean theorem to find the magnitude of the resultant vector and select a suitable trigonometric function to find the angle that the resultant vector makes with the x axis.

- When u need to perform scalar or vector product.It is nice to following procedure
- Select a coordinate system(x,y,z) that is convenient. (Try to reduce the number of components you need to find by choosing axes that line up with as many vectors as possible.).
- Use i,j,k as the unit vector across x,y,z axis.
- Draw a labeled sketch of the vectors described in the problem.
- Express all the vector in form in i,j,k forms
- Perform the multiplication
