The student's ability to understand some basic concepts of the system of Cartesian, spherical and cylindrical unites, identify vectors, vector algebra and some properties on them, as well as the comparison between the plane equation and the straight line equation, and determine the angle bisectors between two planes and straight lines, and to solve all issues related to spatial geometry and connection Between the topics of the course and the previously studied analytical geometry, as well as realizing the importance of this course because many courses depend on it, and he can find the equation of the straight line in space and the equation of the plane in space.
