This year, I took Trigonometry/Probability and Statistics. In the first semester, we studied Trigonometry. Trigonometry is the branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant function of any angle. This class can be very challenging, but at the same time can be very easy. My teacher makes the class a whole lot easier. She is a great teacher, and she explains and works out the problems until we understand them. Ms. Lawson knows exactly what she is doing, and she could probably solve any math problem you gave her. She is a great math teacher, and she is great and what she does. It all depends on the person, whether the class is easy or hard. Some people can instantly pick up on how*…show more content…*

Within the chapter we learned how sine, cosine, tangent, cosecant, secant, and cotangent are graphed. They all have unique graphs. Each of the graphs can be identified by the shape of the lines. A sine graph starts at 0 and has a period of 2π. It also has a domain of (-infinity, +infinity), a range of [-1, +1]. The next type of graph is a cosine graph. This graph has a period of 2π, an amplitude of 1, the zeros are odd, and has multiples of π/2. The domain of a cosine graph is from (-infinity , +infinity) and the range [-1, +1]. A tangent graph is a little different from the first two. This graph has a period of π, no amplitude, and the zeros are multiples of π. This graph also has a vertical asymptote that is at π/2. The domain equals all real numbers except for the vertical asymptote and the range is from (-infinity, +infinity). The next three graphs are the reciprocal of the first three. Cosecant is the reciprocal of sine, secant is the reciprocal of cosine, and cotangent is the reciprocal of tangent. With that being said, a cosecant graph has a period of 2π, no amplitude, no x-intercepts, the vertical asymptote is at the multiples of π, the domain equals all real numbers except for multiples of π, and the range is from (-infinity, -1] U [1, +infinity). The next graph is secant, it has a period of 2π, no amplitude, no x-intercepts, the vertical asymptote is all multiples of π/2, the domain equals all real numbers except for the multiples of π/2, and the range equals ( -infinity, -1] U [1, + infinity). Finally, the cotangent graph. This graph has a period of π, no amplitude, the x-intercepts are odd π/2, the vertical asymptote equal multiples of π, the domain equals all real numbers except the multiples of π, and the range is from (-infinity, + infinity) I learned how to set up a graph. I also learned how to take an equation on a blank graph. This section also taught me how a graph

## Why Is Euler's Formula For Polyhedron?

739 Words | 3 PagesSo, F + V − E = 7 + 8 − 13 and the answer would be 2 which is the expected outcome. Another way to prove the formula does not work for all solids is to take a Icosahedron and connect 2 opposite corners. Joining both corners, the solid will be a Icosahedron but it is not a convex polyhedron. As the soild is not a convex polyhedron should not be 2. So, F + V − E = 20 + 11 − 30, getting the answer as 1 which proves the generalisation F + V − E = 2 does not work.

## Carl Friedrich Gauss: The Fundamental Theorem Of Algebra

1144 Words | 5 PagesA polynomial has been completely factored only if all of its factors are linear or irreducible quadratic. Whenever polynomial are factored into only linear and irreducible quadratics, it has been factored completely since it can’t be factored further over real numbers. For example, when we have n degree polynomials as such function below: p(x) = axn + bxn-1 + ……k The Fundamental Theorem of Algebra will tell us that this n degree polynomials are going to have n-roots or in other way of seeing it, the n value of x will make the expression on the right to be equal to 0. 2. History of root finding The history of root finding dates back during the Islamic Golden Age.

## Snowflake Investigation Report

1650 Words | 7 Pages1. INTRODUCTION Snowflakes, feathery ice crystals that typically display a delicate six-fold symmetry might be the most distinguished mathematical art in the world, from the center of the snowflake, to the outskirts of their anatomy. When inspected, one notices that the different limbs of the snowflakes are mathematically constructed of fractal triangles. With that said, the aim of my exploration is to generate an equation that will aid me in representing a snow flake of any size, in order to do so I would need to explore specific areas of mathematics such as: symmetry, graphical representations, sequences and series and many more. As a consequence I will be focusing on the mathematical concept of: fractal triangles, in order construct my

## Essay On Rational Numbers

1023 Words | 5 Pages1.2.2 Rational numbers All the numbers that we use in our normal day-to-day activities are called Real Numbers. Real numbers are: Positive integers (1, 2, 3, 4, etc.) Fractions (1/2, 2/3, 1/4, etc). [The integers are really forms of fractions (1/1, 2/1, 3/1, etc.)] Negative numbers (-1, -3/4, etc.)

## Pierre De Fermat's Last Theorem

908 Words | 4 PagesHe determined that there was a finite amount of positive integers less than any given positive integer, which led to the proposition famously known as Fermat’s Last Theorem. In modern notation, this contends that if a, b and c are integers greater than 0, and if n is an integer greater than 2, then there are no solutions to the equation: an + bn = cn [3] . For instance, when n is equal to 1 or 2 there exists an infinite amount of integer solutions to the above equation. However, for n greater than or equal to 3, there are no natural numbers for which the statement is true. This equation could also be interpreted as a more general version of the Pythagorean Theorem, as both are concerned with the sums of squares of whole numbers.

## Sodium Thiosulfate And Hydrochloric Acid Lab Report

3578 Words | 15 PagesThere is no linear relationship between X and Y, and the best-fit line is a horizontal line going through the mean of all Y values. When R2 equals 1.0, all points lie exactly on a straight line with no scatter. Knowing X lets you predict Y perfectly. (http://www.graphpad.com/guides/prism/6/curve-fitting/index.htm?r2_ameasureofgoodness_of_fitoflinearregression.htm) In this graph the R2 value is 0.97 which can be rounded off to 1.0 which means that knowing X which in this case is the different concentrations of sodium thiosulfate, predicts the Y which is the time the time the solution turns cloudy resulting X not to be seen from the opening of the conical flask from a person’s eye
