9 trigonometric functions via the unit circle natmath260
The document discusses radian measurements of angles using the unit circle. It defines the unit circle as having a radius of 1 centered at the origin. The radian measurement of an angle is defined as the length of the arc cut out by that angle on the unit circle. Important conversions between degrees and radians are provided. Trigonometric functions like sine, cosine, and tangent are then defined using the unit circle for any real number angle measurement.
1) Radians are a way of measuring angles based on the length of an arc along a circle. To convert radians to degrees, multiply the radian measurement by 180/π.
2) Reference angles are always acute angles formed between the terminal side of a given angle and the x-axis.
3) Coterminal angles are angles that share the same initial and terminal sides and thus represent the same angle position on a unit circle.
The document discusses trigonometric functions like sine and cosine. It defines sine as the ratio of the opposite side to the hypotenuse of a right triangle. Sine's domain is all real numbers and its range is between -1 and 1. Cosine is defined as the ratio of the adjacent side to the hypotenuse. Like sine, cosine's domain is all real numbers and its range is between -1 and 1. The activity asks students to graph the functions f(x) = cos(4x) and f(x) = 2sen(x - 1).

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

3. INTRODUCTION
The word trigonometry is derived
from the Greek words ‘trigon’ and
‘metron’ and it means ‘measuring the
sides of a triangle’
If in a circle of radius ‘ r ’, an arc of
length ‘ l ’ subtends an angle of
radians, then l = r
4. INTRODUCTION
What about angles greater than 90°? 180°?
The trigonometric functions are defined in terms of a
point on a terminal side
r is found by using the Pythagorean Theorem:

12. ALL STAR TRIG CLASS
Use the phrase “All Star Trig Class” to
remember the signs of the trig functions in
different quadrants:
AllStar
Trig Class
All functions
are positive
Sine is positive
Tan is positive Cos is positive
13. The value of any trig function of an angle is equal to
the value of the corresponding trigonometric function of
its reference angle, except possibly for the sign. The
sign depends on the quadrant that is in.
So, now we know the signs of the trig
functions, but what about their values?...
14. REFERENCE ANGLES
The reference angle, α, is the angle between the
terminal side and the nearest x-axis:
