Show full text Several years ago, I created this trigonometry calculator skills pop quiz to give to my Pre-Calculus students before we learn to use our calculators for evaluating trig functions. [CDATA[ Hipparchus, credited with compiling the first trigonometric table, has been described as "the father of trigonometry". Although these tables have not survived, it is claimed that twelve books of tables of chords were written by Hipparchus. Midterm Review - Definitions, Theorems and Postulates. Amplitude, Period, Phase Shift and Frequency. The word trigonometry comes from the Greek words trigonon (triangle) and metron (to measure). Trigonometry helps us find angles and distances, and is used a lot in science, engineering, video games, and more! Articles from Britannica Encyclopedias for elementary and high school students. Test your knowledge of the skills in this course. It is a circle with a radius of 1 with its center at 0. Kids Encyclopedia Facts Trigonometry (from the Greek trigonon = three angles and metron = measure) is a part of elementary mathematics dealing with angles, triangles and trigonometric functions such as sine (abbreviated sin), cosine (abbreviated cos) and tangent (abbreviated tan). [1][2] It has some connection to geometry, although there is disagreement on exactly what that connection is; for some, trigonometry is just a section of geometry. Why doesnt the Pope like trigonometry? The planet Saturn would float on waterit's the only planet in our solar system that would.
