Trigonometric functions are used in obtaining unknown angles and distances from known or measured angles in geometric figures. Trigonometry developed from a need to compute angles and distances in such fields as astronomy, mapmaking, surveying, and artillery range finding.
These identities are derived from the Pythagorean theorem and involve the square of the trigonometric functions:
mathematician Hipparchus The first known table of chords was produced by the Greek mathematician Hipparchus in about 140 BC. Although these tables have not survived, it is claimed that twelve books of tables of chords were written by Hipparchus. This makes Hipparchus…
The origin of zero in India came from a well-known astronomer and mathematician of his time, Aryabhatta. The well-known scientist used zero as a placeholder number. In the 5th century, Aryabhatta introduced zero in the decimal number system and hence, introduced…

Muhammad ibn Musa al-Khwarizmi Muhammad ibn Musa al-Khwarizmi was a 9th-century Muslim mathematician and astronomer. He is known as the “father of algebra”, a word derived from the title of his book, Kitab al-Jabr. His pioneering work offered practical answers for…
To solve a trigonometric equation, we use the rules of algebra to isolate the trigonometric function on one side of the equal sign. Then we use our knowledge of the values of the trigonometric functions to solve for the variable.
The ability to think abstractly and logically that comes from studying Algebra 2 and Trigonometry can open doors to success in many areas, including science, engineering, and technology.
You should already be familiar with algebra and geometry before learning trigonometry. From algebra, you should be comfortable with manipulating algebraic expressions and solving equations. From geometry, you should know about similar triangles, the Pythagorean theorem, and a few other…
They’re regarded as different branches but trigonometry is mostly studied along with algebra II. Algebra II is the third course studied in mathematics at high school and trigonometry is studied with this course or with geometry or calculus.
