conditional statements with p q r

If p and q are two propositions, then the compound proposition, "if p then q" is known as conditional statement or implication. It is denoted by p q. p is called the antecedent (or hypothesis). q is ca..

Logical Equivalence - Two propositions (simple or compound) are said to be logically equivalent if they have identical truth values. If p is logically equivalent to q, we denote p q. We have already constructed the truth table of (~p) q in..

It is already mentioned in earlier classes that compound statements of different propositions can be obtained by conjunction, disjunction and negation of propositions. We just recall these three basic logical connectivities and their truth table and subsequently we shall learn about ..

For all real numbers x and y Let x and y be any two real numbers and let P(x)and Q(y) be the corresponding trigonometric points on the unit circle. In the above figures we have taken x and y so that The coordinates of P(x) are (cosx, sin x) and that of Qh..

If 'n' be any integer then, i) sin (2 p n + q ) = sin q ii) cos (2 p n + q ) = cos ..

What is the product of P, Q, R and S from the number line? => 0.192 or 1.92 or 192 or 19.2..

The locus of a point equidistant from two fixed points is the perpendicular bisector of the segment joining the two points. This theorem is proved in two parts. First prove that any point on the locus satisfies the conditio..

A worm moved 5 inches from P to Q and then another 5 inches from Q to R as shown. Find the shortest distance between P and R. => 25 in. or 5 in. or 5 0 in. or 2 0 in...

OPQR is a Rhombus. Find the coordinates of Q and R, if the coordinates of P are P(3, 6). => (- 6, 0) and ( 3 , - 6 ) or (6, 0) and (- 3 , 6) or ( 0 , 6) and ( - 3 , - 6 ) or (6, 0) and (3 , - 6)..
