Yes, a history textbook is a common secondary source because it is written by a scholar or researcher who has compiled information from various primary sources to create a comprehensive overview of a historical topic. The textbook provides analysis, interpretation, and context to help readers understand the subject matter.
after the events took place.
a textbook is considered as a secondary source. for example, in many social studies textbook it stars or quotes a primary source, it is usually in italic letters.
a textbook, encyclopedia or an interpretation of a diary/ photo unless it is from that specific time period it is a secondary source
Researchers who use secondary sources must make their best efforts to verify the accuracy of the information. For example, a researcher who cites a newspaper article about a court hearing should dig further to verify the information. To do this they may need to get transcripts of the court hearing. It may not always be easy to verify secondary data in research, but every effort must be made in order to prove the credibility of the sources being used in any research. Researchers must also determine the value of secondary sources at times. If no primary sources are available a researcher must use secondary sources. In order to use credible secondary sources and retrieve honest and accurate information a researcher must validate the sources by evaluating them thoroughly. To evaluate secondary sources a researcher must consider the purpose, scope, authority, and audience that the information is based on (Cooper & Schindler, 2006, Ch. 7). Determining these factors will help a researcher choose secondary sources that have strong value. Secondary data is a source that many researchers will have to use at times. Using secondary data as the only available resource can cause problems of verification and credibility. This makes a researcher's job harder. Although the use of secondary resources can bring extra work, it must be done at times. For a researcher to get past the problems of credibility presented by secondary resources a researcher must take steps to verify secondary sources. A researcher must also make well thought out judgments on secondary resources if they want their research to appear credible and valid. Understanding the problems with secondary research data is the first step in determining how to deal with these problems.
Secondary sources of information include books, journal articles, newspapers, magazines, and websites that interpret, analyze, or comment on primary sources. For example, a textbook discussing the historical events of World War II would be considered a secondary source of information.

A primary text is a text where the source was personal or direct. For example, a primary text would be an anecdote or autobiography. Quoting a speech directly, or describing an experience that the writer experienced THEMSELF would also be classified as a primary text. A secondary text ideally makes reference to a primary text. A history textbook may directly relay events in history (primary text), but a project based on the readings of this textbook would be a secondary text. Going even further, an essay based on the project, based on the textbook, based on actual events in history should be classified as perhaps a "tertiary" text. However, it is simply termed "secondary". A secondary text is any text that is not directly from the source.
I think it is an example of an infectious disease...or so it says in my textbook!
please give me an answer, I'm from Srilanka.
Crocodiles are generally considered to be secondary or tertiary consumers because their diet is composed primarily of other animals, which may be primary or secondary consumers themselves. Example: A crocodile eats a gazelle, which eats grass. In this example, the crocodile is a secondary consumer.
Primary would be the first of whatever you're talking about, and secondary would be the second or the once-removed whatever it is. For example, a primary source of research would be something like a diary or letter, which would be a first-line information source - a secondary source would be a textbook reporting about what the person described in the letter or diary.
An example is a snake that eat reabbits
