Crear una tabla de verdad para una expresión lógica de la forma :

\[[(a \ {op1}\ b) \ {op2}\ (c \ {op3}\ d)] \ {op4} [e\ {op5}\ f]]\]

donde cada una de $a, \; b, \; c, \; d, \; e, \; f $ puede ser una de las variables booleanas \[ p, \; q, \; \neg p, \; \neg q\]  y cada uno de los operados $\ {op} $  puede ser uno de los operadores $ \lor, \; \land, \; \to $.

Crear una tabla de verdad para una expresión lógica de la forma:

$$(a \ {op1}\,\  b) \ {op2}\,\ (c \ {op3} \,\ d)$$

donde $a, \;b,\;c,\;d$ pueden variables booleanas $p,\;q,\;\neg p,\;\neg q$  y cada operador  $\operatorname{op1},\;\operatorname{op2},\;\operatorname{op3}$  es uno de los conectivos $\lor,\;\land,\;\to$.

Por ejemplo: $(p \lor \neg q) \land(q \to \neg p)$.

This question demonstrates how to construct a JSXGraph diagram using JessieCode.

The construction shows a triangle and its orthocentre, circumcentre and centroid. They are always collinear. You can move the vertices of the triangle.

Evaluating arithmetic operations, and the order of operations.

Two quadratic graphs are sketched with some area beneath them shaded. Question is to determine the area of shaded regions using integration. The first graph's area is all above the $x$-axis. The second graph has some area above and some below the $x$-axis.
