## Introduction to Inverse Trigonometric Functions

– WELCOME TO AN INTRODUCTION TO INVERSE TRIGNOMETRIC FUNCTIONS. THE GOALS OF THE VIDEO ARE TO USE INVERSE TRIG FUNCTIONS TO FIND AN ANGLE OF A GIVEN TRIGNOMETRIC FUNCTION VALUE, AND ALSO TO USE INVERSE TRIGOMETRIC FUNCTIONS TO SOLVE A RIGHT TRIANGLE. REMEMBER, YOU CAN THINK OF A FUNCTION AND ITS INVERSE FUNCTION AS TWO…

## Graphing Absolute Value Functions as Piecewise Functions 3 Examples

Bam Mr. Tarrou In this lesson we’re going to be taking a look at graphing three examples of absolute value functions as piecewise functions when you go into calculus this may be very well be an algebra 2 honors course or precalculus course when you step into calculus it’s going to be important that we…

## Composite Functions

– WELCOME TO A VIDEO ON COMPOSITE FUNCTIONS. A COMPOSITE FUNCTION CAN BE THOUGHT OF AS A COMBINATION OF TWO FUNCTIONS. ONE WAY TO ILLUSTRATE THIS WOULD BE TO USE A CONVEYOR BELT WHERE WE HAVE AN INITIAL INPUT OF, LET’S SAY, 3, ONE WAY TO ILLUSTRATE THIS WOULD BE TO USE A CONVEYOR BELT…

## What are some real-world examples of functions? – Week 1 – Lecture 4 – Mooculus

[MUSIC] So, there’s all these different ways of taking two functions and producing new functions. You could add, subtract, multiply, divide two functions, and could take two functions and compose them, meaning that the output for the one becomes the input for the other. In light to this, I’d encourage you just to pick up…

## Programming Basics: Statements & Functions: Crash Course Computer Science #12

Hi, I’m Carrie Anne, and welcome to CrashCourse Computer Science! Last episode we discussed how writing programs in native machine code, and having to contend with so many low level details, was a huge impediment to writing complex programs. To abstract away many of these low-level details, Programming Languages were developed that let programmers concentrate…

## Input Output Tables Song | 4th Grade | Finding the Rule of A Function

We’re in a hot air balloon going up to fly; a table shows our time and height in the sky. At one minute, We’re three meters off the ground; at two minutes, We’re six meter’s up, staring down. At three meters, We’re up nine meters high. What’s the “rule” that shows our place in the…
