# Precalculus with Limits Answers

Posted on

In Mathematic education, precalculus is the study of a complex branch of mathematics including algebra, analytical geometry and trigonometry. In the schools, algebra and trigonometry are two separate parts of the coursework.

Precalculus aims to prepare the students to handle dynamic and rigorous concepts by helping them to connect their previous learning from Geometry and Algebra. Considering the Precalculus practices are a bit hard to complete, the students may need the answer keys for Precalculus tests.

So, can you get the Precalculus with limits answers? No worries! This post will show you a list of Precalculus answer keys. Let’s find out the Precalculus with limits answers from our post below!

Chapter 1: Functions and Their Graphs Answers

1. An ordered pair of real numbers can be represented in a plane called the rectangular coordinate system or the…………… plane.

The answer is cartesian

1. The point of intersection of the x- and y-axes is the (1), and the two axes divide the coordinate plane into four parts called (2)

The answer is (1) origin and (2) quadrants

1. The …………… is a result derived from the Pythagorean Theorem.

The answer is distance formula

Chapter 2: Polynomial and Rational Functions Answers

1. Linear, constant, and squaring functions are examples of ……. functions

The answer is polynomial

1. ………….. is negative and the vertex is maximum, when the graph of a quadratic function is opened downward.

1. Let us find the vertex of the given function:

Ax2 + bx + c2 = = x2− 2

The answer is: The vertex is (0, −2). Therefore, the right graph is graph b

Here’s for the explanation: Chapter 3: Exponential and Logarithmic Functions Answers

1. Algebraic (See algebraic functions, page 380)
2. Transcendental (See transcendental functions, page 380)
3. One-to-One (See the One-to-One property, page 382)
4. Natural exponential(See the natural exponential function, page 384)
5. A = Pert(See the formula for compounded interest, compounded continuously, page 386)

Chapter 4: Trigonometry Answers

1. Coterminal (See page 444)
2. Fill the blank! By definition, the measure of a central angle α that intercepts an arc equal to the radis ‘r’ of the circle is….

1. Two angles that have a sum of 90∘or π/2 radians are (1) Two angles that have a sum of 180∘or π radians are (2)

The answer is (1) complementary (2) supplementary

Chapter 4: Trigonometry Answer

1. This is one of the fundamental trigonometric identities.

The answer is tan u.

Here’s for the explanation: 1. We know that tan u = cos u/ sin u, so we have?

The answer is cotu

Here’s for the explanation: 1. Let 1 + x = csc2u

The answer is cot2 u

Here’s for the explanation: Chapter 5: Analytic Geometry Answers

1. An equation that is true for all real values in its domain is called ……..

The answer is an identity

1. An equation that is true for only some values in its domain is called……..

The answer is a conditional equation

1. To solve the trigonometric equation we need to …… the trigonometric function.

The answer is isolate

Chapter 6: Additional Topics in Trigonometry Answers

1. On page 402 we can see the definition of oblique triangles.

The answer is oblique

1. Given△ABC where∠C= 105°, ∠B= 45° and b = 20. How to find ∠A, remember that the sum of the interior angles of a triangle is equal to 180°? 1. We would like to solve the triangle using the Law of Sines where A= 35o,B= 40oand C=10. What is the answer? Chapter 7: Systems of Equations and Inequalities Answers

1. The …… of a system of equations is an ordered pair which satisfies each equation in the system.

The answer is solution (found on page 654)

1. We will determine if ordered pair (0, −4) is solution of the system

2x − y = 4

8x + y = −9 1. We will determine if ordered pair (-1/2, 5) is a solution of the system:

2x − y = 4

8x + y = −9 Chapter 8: Matrices and Determinants Answers

1. The plural of “……” is “matrices”.

The answer is Matrix

1. ……, the order of a matrix is by rows and columns.

The answer is Square

1. We read matrices by Rows⋅Columns

The answer is One row: Row matrix and One column: Column matrix

Chapter 9: Sequences, Series, and Probability Answers

1. An …….. is when a sequence has no end, and the domain (limits) are any positive

integers, such as a1, a2, a3, a4, a5… and so on.

The answer is infinite sequence

1. A …… is when the sequence has an end, such as a1, a2, a3, a4, a5.

The answer is finite sequence

1. When we want to ….. define a sequence, we define the first few terms, hence all the following terms of the sequence are defined by previous terms.

The answer is recursively
