On the New York State Algebra 2/Trigonometry regents examination, it is recommended to get at least 20 of the 27 part I multiple choice questions correct. When you reach the Part II, III, and IV there are 12 question remaining for a total of 39 questions on the examination. Part IV is the last section, containing 1 question which is arguably the longest and most difficult on the test. The grading and conversation chart changes per each test, but is recommended to get at least 7 of the 12 Part II,III, and IV correct (however it varies per question how many points each question is worth.) That is the basic outline of the exam, and each student is given 3 hours to complete the examination. Good luck if you are taking it.

Why do you need to study trigonometry?
Trigonometry is essential to the study of higher mathematics (calculus) and to the understanding of many scientific and engineering principles. Trigonometry and calculus can be used to model many shapes, motions, and functions in daily life.
How many kinds of trigonometry are there in mathematics?
Two types of trigonometry are recognized: planar and spherical. Planar is 2-dimensional, while spherical is 3-dimensional. Though these are different fields, spherical trigonometry is really just an application of planar trigonometry in several planes.
How is trigonometry ues today?
Trigonometry is used in the design and construction of buildings, cars, planes, and many other objects. Trigonometry is used in physics and engineering whenever forces, waves, fields, and vectors are involved. Trigonometry is used in music and acoustics to design speakers, instruments, and concert halls. Trigonometry is used to coordinate launches OS space shuttles. Trigonometry is used to navigate ships and planes. Nearly every part of modern life uses trigonometry in some way.
How many formulas in trignometry?
Loads and loads of formulas. That's trigonometry. ;-)
How do crime scene investigators use trigonometry?
Trigonometry is used in CSI in calculating bullet or other projectile trajectories, ballistics, analyzing what actually happened in automobile collisions, how objects fall from heights, and in many many other ways.
