Calculus: Early Transcendentals, originally by D. Guichard, has been redesigned by the Lyryx editorial team. Substantial portions of the content, examples, and diagrams have been redeveloped, with additional contributions provided by experienced and practicing instructors. This approachable text provides a comprehensive understanding of the necessary techniques and concepts of the typical Calculus course sequence, and is suitable for the standard Calculus I, II and III courses.
To practice and develop an understanding of topics, this text offers a range of problems, from routine to challenging, with selected solutions. As this is an open text, instructors and students are encouraged to interact with the textbook through annotating, revising, and reusing to your advantage. Suggestions for contributions to this growing textbook are welcome.

Lyryx develops and supports open texts, with editorial services to adapt the text for each particular course. In addition, Lyryx provides content-specific formative online assessment, a wide variety of supplements, and in-house support available 7 days/week for both students and instructors.

This course is an introduction to the calculus of functions of several variables. It begins with studying the basic objects of multidimensional geometry: vectors and vector operations, lines, planes, cylinders, quadric surfaces, and various coordinate systems. It continues with the elementary differential geometry of vector functions and space curves. After this, it extends the basic tools of differential calculus - limits, continuity, derivatives, linearization, and optimization - to multidimensional problems. The course will conclude with a study of integration in higher dimensions, culminating in a multidimensional version of the substitution rule.

This contemporary calculus course is the third in a three-part sequence. In this course students continue to explore the concepts, applications, and techniques of Calculus - the mathematics of change. Calculus has wide-spread application in science, economics and engineering, and is a foundation college course for further work in these areas. This is a required class for most science and mathematics majors.Login: guest_oclPassword: ocl

This course is an introduction to differential and integral calculus. It begins with a short review of basic concepts surrounding the notion of a function. Then it introduces the important concept of the limit of a function, and use it to study continuity and the tangent problem. The solution to the tangent problem leads to the study of derivatives and their applications. Then it considers the area problem and its solution, the definite integral. The course concludes with the calculus of elementary transcendental functions.

This course is a brief introduction to sequences and infinite series. We begin with a discussion of power series and develop tests for convergence and non-convergence. Taylor series are introduced and lead to an analysis of power series in general. This is a 1-credit course that can be taken any time after the student has completed Calculus I.

This is a Principles of Macroeconomics course utilizing exclusively Open Educational Resources and designed in Canvas. This course is mapped to the Learning Outcomes for ECON 2301 as established under the Texas Higher Education Coordinating Board Academic Course Guide Manual. This course is based on Openstax Principles of Macroeconomics 2e textbook and incorporates key components from EDUC 1301: Learning Frameworks, designed to enhance the student’s experience as well as to improve overall student learning.
The course was developed by a faculty team from Collin College as part of the Texas Higher Education Coordinating Board OER Course Development and Implementation Grant Program.

The national Great Depression had a large effect on Texans. The Relief, Recovery, and Refom programs of the New Deal made changes to the Texas economy and social conditions. The Dust Bowl in the Texas Panhandle aggravated conditions there.

Texas played a big role in WWII, from defense industries to fighting on the front lines. The war effort involved almost every Texan in some ways, and the accomodations led to major economic, social, and political shifts.

The increase of urbanization helped spark the Civil Rights movements in Texas. African Americans, Mexican Americans, women, and other groups all fought for equal rights with varying success. As more groups moved toward equality, political parties found other issues to advance.

Texas changed from a one-party Democratic state to a one-party Republican state with the 1980 presidential election of Ronald Reagan. Conservative Democrats felt the national Democratic party had become too liberal and out-of-touch with issues facing many Texans and so became conservative Republicans. As the GOP took control of both houses of the legislature and the governor's office most of the time, laws and policies became increasingly conservative.

As Texas modernized, it became more and more like the rest of the United States, with large metropolises and metroplex, technological and medical industries, and more. Few Texans remained in rural areas, fewer still had jobs directly related to agriculture. National issues like immigration had a profound effect on Texas politically, socially, and economically.

The people living in Texas before European contact had to survive in different conditions, from beaches to mountains, forests to deserts. A wide diversity of life existed. From the complex society of the Caddoes of East Texas, to the trading culture of the Antelope Creek society in the Panhandle, to the warlike, barely surviving society of the coastal Karakawas, Native Americans adapted to their surroundings.

The Spanish came to Texas first by accident, then by exploring to find gold or silver. Later, they came to form a buffer between French Louisiana and their rich mines in Mexico and New Mexico. The Spanish had few settlements based on the mission/presido system. These were decimated in hthe war for Mexican independence. Nevertheless, the Spanish had a lasting influence on Texas, with many place names, land laws, and women's rights.

People living in Texas were affected by the Mexican War for independence and the early struggles for a stable government in Mexico. Mexicans invited people from the Unites States to colonize using empresario grants. The purpose for the Mexican government was to have the Anglos (not Mexicans) deal with hostile Indians. Austin Moses, and when he died his son Stephen, got the first and most succesful of these grants and Anglo colonization began. People from the southern US came to Texas to raise cotton and many brought their slaves to do all the work. Over time, former US citizens grew frustrated with the Mexican government and began to want to make Texas part of the US.

The Texas Revolution was based on the desires of colonists from the US to retain the forms of government they were used to and the need to use slaves to make cotton-raising profitable. The revolution was over quickly with only a few battles. Texans expected to be annexed immediately into the US and when that did not happen, the scramble to set up the Republic of Texas began. The Republic lasted nine years and was never very successful. In 1845, Texas was finally annexed into the US as a state.
