Law of tangents
In trigonometry, the law of tangents is a statement about the relationship between the tangents of two angles of a triangle and the lengths of the opposing sides.
In Figure 1,,, and are the lengths of the three sides of the triangle, and,, and are the angles" opposite" those three respective sides.
The law of tangents states that The law of tangents, although not as commonly known as the law of sines or the law of cosines, is equivalent to the law of sines, and can be used in any case where two sides and the included angle, or two angles and a side, are known.
Law of reciprocal proportions
The law of reciprocal proportions( also called law of equivalent proportions or law of permanent ratios) is one of the basic laws of stoichiometry.
It relates the proportions in which elements combine across a number of different elements.
It was first formulated by Jeremias Richter in 1791.
A simple statement of the law is :-
The acceptance of the law allowed tables of element equivalent weights to be drawn up.
These equivalent weights were widely used by chemists in the 19th century.
The other laws of stoichiometry are the law of definite proportions and the law of multiple proportions.
The law of definite proportions refers to the fixed composition of any compound formed between element A and element B.
The law of multiple proportions describes the stoichiometric relationship between two or more different compounds formed between element A and element B.

Law of noncontradiction
In logic, the law of non-contradiction( LNC)( also known as the law of contradiction, principle of non-contradiction( PNC), or the principle of contradiction) states that contradictory propositions can not both be true in the same sense at the same time, e. g. the two propositions A is B and A is not B are mutually exclusive.
Formally this is expressed as the tautology ¬( p ∧ ¬p).
One reason to have this law is the principle of explosion, which states that anything follows from a contradiction.
The law is employed in a reductio ad absurdum proof.
To express the fact that the law is tenseless and to avoid equivocation, sometimes the law is amended to say" contradictory propositions can not both be true' at the same time and in the same sense'".
It is one of the so called three laws of thought, along with its complement, the law of excluded middle, and the law of identity.
The law of noncontradiction is logically equivalent to the law of excluded middle by De Morgan's laws.
However, no system of logic is built on just these laws, and none of these laws provide inference rules, such as modus ponens or De Morgan's laws.
The law of non contradiction and the law of excluded middle create a dichotomy in" logical space", wherein the two parts are" mutually exclusive" and" jointly exhaustive".
The law of non-contradiction is merely an expression of the mutually exclusive aspect of that dichotomy, and the law of excluded middle, an expression of its jointly exhaustive aspect.
