here is a link to a simple calculator in lex and yacc, implementing something like our example expression grammar calculator

This is calc.lex and calc.yacc from Andrew Brinker – you may use these as youy starting point instead of the first link

1. Implement it

> 2. Add and exit/quit feature, so that you can enter one expression and then use the result as the start of another expression – for example:

2+5 => 7

/2 => 3.5

3. Add variables to the grammar – this requires modifying the grammar with an assign statement so you can set the values of a variable, and a print ot display statement so you can view the contents of the variable. You may implement it as an interpreter or a compiler

Hello again, I have 2 assignments for your assistance. Here is the first 

– Discussion 5: Interpretation (Multimedia, Installation and Performance Art)

– This assignment continues your journey from Weeks 1 through 4 about learning how to see and compare/contrast, but now encouraging you to interpret.

– Choose any image from the list below and do a formal analysis (Discuss, as needed, Line, Shape and Form, Space, Texture, Value and Light, Color, Time, Repetition, Variety, Rhythm, Balance, Compositional Unity, Emphasis, Economy and/or Proportion). – Then, based on your own independent research through scholarly websites or books, consider any of the following, in detail:

symbolism, political meaning,theological meaning,sociological meaning,philosophical meaning.- Try to help us understand how any of these factors can be seen in the image you choose, i.e. where is the symbolism or the political meaning? How so?

– Select any one image from the following.Ron Mueck, “In Bed,” (Zalenski/Fisher, p. 17)W. Eugene Smith, “Tomoko in a Bath,” 1972 (Zalenski/Fisher, p.34)Dary Jampijimpa, “Burrowing Skink Dreaming”, 1986 (Zalenski/Fisher, p. 40)Soo-ja Kim, “Lie on the Nature,” 1994 (Zalenski/Fisher, p. 43) Note: this is an image from a performance piece.Jackson Pollack “Number 1, 1948”, 1948 (Zalenski/Fisher, p. 46)Diego Rivera, “Flower Day”, 1925 (Zalenski/Fisher, p. 19)Piet Mondrian, “Composition (B) en Bleu, Jaune at Blanc,” 1936 (Zalenski/Fisher, p. 21)

– Remember: look closely. Look at other reproductions of the image on the web to look even closer. Be very detailed and use the terminology you are learning from your readings within each category. But now interpret! Cite the URL of the web page you are looking at.

– Basically it’s just like the previous assignments, just different subject matter, Thank you for your help!

Here is the DF  2 and DF3

As you have been seeing so far, even though many mathematical theorems were derived in Greece, other parts of the world have had their fair share of theorems as well. Based on the theorems you have learned in this module, choose one that interests you the most. Describe the theorem in more depth. In addition, as like the first discussion, provide an example of the theorem as it is used in anything you have learned so far in the subject.

Df3

Until the 17th century, there was no such thing as Calculus. This is thanks to Newton and Leibniz. Discuss how Calculus changed the face of mathematics. Then, choose a Calculus theorem and discuss it in more depth.
