CBSE - XI Science - Mathematics - Introduction to Three Dimensional Geometry
could u plzz give me any idea for a nice maths model for 11th std .. and write the steps to make it. it may not be realted to the given chaptr and topic... somethng nice
1) A working model of theodolite can be made.
A theodolite is an instrument used for determining the horizontal and vertical angles between two points. It is a key tool in surveying and engineering work, particularly on inaccessible ground.
If the distance between two point in a triangle is known, and two angles are measured using the theodolite, each dimension of the triangle can be determined using the triangulation process.
2) A working model of clinometer can be made.
A clinometer is a fairly simple instrument which is used to measure the angle of a slope. By using the principles of trigonometry, the height of tall objects can be calculated from the angles measured.
