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!

 An ordered pair of real numbers can be represented in a plane called the rectangular coordinate system or the…………… plane.
The answer is cartesian
 The point of intersection of the x and yaxes is the (1), and the two axes divide the coordinate plane into four parts called (2)
The answer is (1) origin and (2) quadrants
 The …………… is a result derived from the Pythagorean Theorem.
The answer is distance formula
Chapter 2: Polynomial and Rational Functions Answers
 Linear, constant, and squaring functions are examples of ……. functions
The answer is polynomial
 ………….. is negative and the vertex is maximum, when the graph of a quadratic function is opened downward.
The answer is Leading coefficient
 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

The answer is radian
 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
 This is one of the fundamental trigonometric identities.
The answer is tan u.
Here’s for the explanation:
 We know that tan u = cos u/ sin u, so we have?
The answer is cotu
Here’s for the explanation:

 Let 1 + x = csc2u
The answer is cot2 u
Here’s for the explanation:
Chapter 5: Analytic Geometry Answers
 An equation that is true for all real values in its domain is called ……..
The answer is an identity
 An equation that is true for only some values in its domain is called……..
The answer is a conditional equation
 To solve the trigonometric equation we need to …… the trigonometric function.
The answer is isolate
Chapter 6: Additional Topics in Trigonometry Answers
 On page 402 we can see the definition of oblique triangles.
The answer is oblique
 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°?
The answer is
 We would like to solve the triangle using the Law of Sines where A= 35o,B= 40oand C=10. What is the answer?
The answer is
Chapter 7: Systems of Equations and Inequalities Answers
 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)
 We will determine if ordered pair (0, −4) is solution of the system
2x − y = 4
8x + y = −9
The answer is
 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
 The plural of “……” is “matrices”.
The answer is Matrix
 ……, the order of a matrix is by rows and columns.
The answer is Square
 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
 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
 A …… is when the sequence has an end, such as a1, a2, a3, a4, a5.
The answer is finite sequence
 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
