1. The principles of calculus, historically, are differentials and integrals [1], while those of algebra are operators and equation solving [2]. Contemporary principles are analysis and abstract objects, respectively.

As an example case, why is relational algebra not called a calculus, and why is the -calculus not called an algebra?

. Using the examples for Algebra, do the following: - - Graph the function f(x) = | sin x| on the interval [-2, 2]. - - Graph the equation x/2+y/2 = 1. Using the examples for Plotting and Graphics, do the following: Factorize the polynomial x - 2x - 4. Solve the equation x = 2x + 4 for x. Find the range of the function f(x) = sin x + cosx. Using the examples for Calculus and Analysis, do the following: Find - - - d dx Calculate (sec x tan x). J ca Calculate sec x dx. [a-x dx.
