Get the 2nd edition; the 3rd edition is watered down. For trig, I prefer Gelfand; however, knowledge of geometry is required. There are better books for gwometry, such as Kisselev planimetry, but there are no answers in the back, and the book is rather terse. I think I’ll go with Charles P for trigonometry, but I’ve heard it’s almost too basic, so maybe Ron Larson is better, I’m

I would recommend Gelfand for trig; I assume you haven’t done geometry yet? You can read most trig books without a geometry background, but knowledge of geometry is required for a better understanding. The 3rd edition eliminates two-column proofs, making it easier. Does Harold Jacobs do a good job of being clear and introducing subjects without assuming too much?

## What should I study before trigonometry?

Before learning trigonometry, you should be familiar with algebra and geometry. In algebra, you should be comfortable manipulating algebraic expressions and solving equations; in geometry, you should be familiar with similar triangles, the Pythagorean theorem, and a few other things, but not a lot.

## What age is trigonometry for?

In general, trigonometry is studied in sophomore or junior year math, and it is frequently incorporated as a unit or semester focus in other math courses.

## Is trigonometry easier than geometry?

Algebra 2/trig is a little more difficult, but it’s not too bad if you keep up with your work on a daily basis. I found geometry to be easier than any of the other math courses in high school; in order of difficulty, Algebra I, Geometry, Algebra II, and then Trigonometry.

## What are the basics of trigonometry?

Trigonometry Fundamentals The sine, cosine, and tangent are the three basic functions in trigonometry, from which the other three functions of cotangent, secant, and cosecant are derived, and all trigonometrical concepts are derived.

## In what order should you learn math?

In high school, math classes are usually taken in the following order:

- Pre-Calculus.
- Calculus.
- Algebra 1.
- Geometry.
- Algebra 2/Trigonometry.

## Is trig harder than calculus?

The rigorous study of calculus can be challenging; however, if you’re talking about “computational” calculus, it’s a lot easier; on the other hand, computational trig as it’s taught in high school is a lot easier.

## Is Algebra 2 a prerequisite for trigonometry?

Unlike Algebra II, which is primarily used in probability and statistics, Trigonometry has applications in the sciences, including astronomy, navigation, engineering, physics, and geography. Trigonometry is a prerequisite for calculus.

## Why is calculus so hard?

Calculus is a bogeyman of sorts for students because it is at a slightly higher conceptual level than pre-calculus and (high school) algebra, and it requires a lot of work doing practice problems, which a lot of people aren’t willing to do.

## Who is a father of trigonometry?

Hipparchus, who is now known as “the father of trigonometry,” is said to have created the first trigonometric table.

## What is reciprocal of sin?

The cosecant is the ratio of the hypotenuse to the side opposite a given angle in a right triangle, and it is the reciprocal of the sine.

## What math do 12th graders take?

Most students will have completed Algebra I, Algebra II, and Geometry by the 12th grade, so high school seniors may want to concentrate on a higher level mathematics course like Precalculus or Trigonometry, where they will learn concepts such as graphing exponential and logarithmic functions.

## What is the hardest math ever?

The 10 Most Difficult Math Problems Ever Solved

- Dave Linkletter’s Collatz Conjecture.
- Goldbach’s Conjecture Creative Commons.
- The Twin Prime Conjecture.
- The Riemann Hypothesis.
- The Birch and Swinnerton-Dyer Conjecture.
- The Kissing Number Problem.
- The Large Cardinal Project.

## Why is algebra 2 so hard?

Algebra 2 is perceived to be difficult by students because it builds on and combines material from many previous math classes, including Algebra 1.

## Can you skip geometry in high school?

It may be possible to skip geometry or take both at the same time if your schedule allows; in either case, I recommend that you do some extra geometry to ensure that your knowledge is adequate. High school personnel are notorious for repeatedly rejecting reasonable requests; don’t take no for an answer.
