Essential trigonometric identities-Physics NEET/JEE/CUET revision
TRIGONOMETRIC IDENTITIES TRIGONOMETRY: What exactly is trigonometry? Trigonometry is primarily concerned with angles and triangles.The study of angles and how they affect various quantities and measures is known as trigonometry.Trigonometry is used to learn about triangles and their relationships What are the trigonometric applications? The trigonometric method is used to determine the height of a building or mountain, as well as the length of a beam required to span a specific distance. The trigonometry method is used to calculate an object's torque and forces.Engineers use trigonometric methods to solve design and construction problems involving structures such as bridges and buildings. A navigation method that calculates the distance between a receiver and a satellite using the law of cosines. Trigonometric methods are used by astronomers to calculate the distances of stars and planets from Earth. Physicists use trigonometry to study wave behaviour, analyse signals, and predict ...
HOW INTERNAL RESISTANCE OF A LECHLANCHE CELL IS CALCULATED USING A POTENTIOMETER ?
INTERNAL RESISTANCE OF A LECHLANCHE CELL : CIRCUIT DIAGRAM: AB -Potentiometer Bt -Battery Eli K 1 K 1 -Plug key in the primary circuit K 2 -Plug key in the secondary circuit Rh -Rheostat L (or) E -Lechlanche cell H.R -High Resistance G - Galvanometer R -Resistance box J 1 , J 2 -Pencil Jockey positions EXPERIMENTAL SET UP: SIMPLE CIRCUIT DIAGRAM : PROCEDURE: The circuit associations and the test set up are made as displayed previously. In the open circuit,when resistance is excluded (not included), the emf of the cell is deterimned by taking note of the balnc...
