## Example: Graphing the Tangent Function Using the Unit Circle and the Reciprocal Identity

– WELCOME TO AN EXAMPLE OF GRAPHING THE TANGENT FUNCTION USING THE UNIT CIRCLE AND THE RECIPROCAL IDENTITY. TANGENT THETA IS EQUAL TO SINE THETA DIVIDED BY COSINE THETA. SO ON THE UNIT CIRCLE IT’S EQUAL TO Y DIVIDED BY X. NOW, THERE ARE SEVERAL WAYS TO GRAPH THE TANGENT FUNCTION. THIS IS JUST ONE…

## Ex: Quadratic Function Application – Horizontal Distance and Vertical Height

– THE EQUATION Y=-ONE SIXTEENTH X SQUARED + 4X +3 MODELS THE HEIGHT OF AN ARROW WHERE X IS THE HORIZONTAL DISTANCE IN FEET FROM THE POINT THE ARROW IS SHOT. SO Y REPRESENTS THE HEIGHT IN FEET AND X REPRESENTS THE HORIZONTAL DISTANCE TRAVELED IN FEET. WE WANT TO ANSWER THE FOLLOWING THREE QUESTIONS….

## Ex 2: The Difference Quotient (Quadratic Function)

– WELCOME TO A SECOND EXAMPLE OF DETERMINING THE DIFFERENCE QUOTIENT FOR A GIVEN FUNCTION. IN THIS EXAMPLE, THE GIVEN FUNCTION IS A QUADRATIC FUNCTION AND AS MENTIONED IN EXAMPLE 1, THIS DIFFERENCE QUOTIENT OR THIS QUOTIENT HERE IS A VERY IMPORTANT QUOTIENT IN THE STUDY OF CALCULUS, BUT FOR THIS EXAMPLE WE’RE JUST WORKING…

## Ex: Graph an Exponential Function and Logarithmic Function

– WE WANT TO GRAPH THE EXPONENTIAL FUNCTION Y=2 RAISED TO THE POWER OF X, AND THE LOG FUNCTION Y= LOG BASE 2 OF X ON THE SAME COORDINATE PLAIN. THEN WE’LL DISCUSS THE RELATIONSHIP BETWEEN THE TWO FUNCTIONS. TO GRAPH THESE FUNCTIONS, WE’LL GRAPH THEM BY HAND BY COMPLETING A TABLE OF VALUES. SO…

## Ex 2: Determine the Function From the Graph of a Piecewise Defined Function

– WELCOME BACK TO A SECOND EXAMPLE OF DETERMINING THE FUNCTION RULE FOR A PIECEWISE DEFINED FUNCTION GIVEN THE GRAPH. THE FIRST THING WE SHOULD RECOGNIZE FROM OUR GRAPH IS THAT WE HAVE THREE PIECES, SO WE’LL HAVE TO HAVE THREE FUNCTION RULES FOR OUR PIECEWISE DEFINED FUNCTION. WORKING FROM LEFT TO RIGHT, WE’LL HAVE…

## Derivative of Inverse Functions Calculus 1 AB READ DESCRIPTION

Bam! Mr. Tarrou In this Calculus lesson we are going to be doing a lot of review which will be nice. We are actually…. A lot of what we are learning in Calculus is review. Like we first started talking about derivatives and really just went all the way back to algebra 1 and started…

## How to use the HLOOKUP function in Excel

HLOOKUP is one of Excel’s more powerful Lookup functions If your data is organized into horizontal rows, you can use the HLOOKUP function to search for a value in the first row of your data table and return a corresponding value from another row The easiest way to understand this function is to look at…
