## Graphing a Piecewsie Defined Function with a Graphing Calculator

this video relook at how-to used thirty eight forty graph piecewise defined function and then use that function calculates and values here’s our piece was defined function in vancouver graphing calculator they were going to go into the white mls the photograph exporter minus four and will be all this in the standard when mister […]

## Ex: Evaluate Common Logarithms on the Calculator

– WE WANT TO EVALUATE EACH LOGARITHM ON A CALCULATOR. THEN WRITE A EXPONENTIAL EQUATION TO SHOW THE MEANING OF THE VALUE. NOTICE IN BOTH OF THESE LOGARITHMS THE BASE IS NOT GIVEN THEREFORE WE KNOW IT’S A COMMON LOGARITHM OR LOG BASE 10. MOST CALCULATORS ONLY CONTAIN TWO LOG BUTTONS, LOG FOR COMMON LOG […]

## Ex: Evaluate Natural Logarithms on the Calculator

– WE WANT TO EVALUATE THE GIVEN LOGARITHMS, AND THEN WRITE AN EXPONENTIAL EQUATION TO SHOW THE MEANING OF THE VALUE. NOTICE BOTH OF THESE ARE NATURAL LOGARITHMS, WHICH MEANS BOTH OF THESE ARE LOG BASE E. AND JUST TO REMIND US OF THIS, LET’S GO AHEAD AND PUT THE LITTLE E HERE AND HERE. […]

## C# Tutorial: Equation Calculator++ [Trigonometric Functions]

Create a new method If it’s a digit then return the double c – cos ; t – tan ; s – sin index +=4 (jump over 4 chars, 3 from trigfunction name and 1 is the open parenthesis) Jump over the closing parenthesis (but make sure the index is not equal to expr length) […]

## Ex: Evaluate arccot(-3.6) Using a Calculator

– WE WANT TO EVALUATE ARCCOTANGENT OF -3.6, WHICH MEANS WE WANT TO DETERMINE AN ANGLE THAT HAS A COTANGENT FUNCTION VALUE OF -3.6/1. NOW, THERE ARE AN INFINITE NUMBER OF ANGLES THAT HAVE A COTANGENT FUNCTION VALUE OF -3.6, BUT THE OUTPUT OR RANGE FOR ARCCOTANGENT IS ON THE OPEN INTERVAL FROM 0 TO […]

## Ex 1: Evaluate Logarithms Without a Calculator – Whole Numbers

– WE WANT TO EVALUATE THE TWO GIVEN LOGARITHMS WITHOUT THE USE OF A CALCULATOR. WE HAVE LOG BASE 3 OF 81 AND LOG BASE 2 OF 32. TO EVALUATE THESE WE’RE GOING TO SET THEM EQUAL TO A VARIABLE, LET’S SAY X, THEN WE’LL WRITE THIS AS AN EXPONENTIAL EQUATION TO DETERMINE THE VALUE […]

## C# Tutorial: Equation Calculator [Expression Evaluator]

First create a method/function that will return a double from the string ref – means the param it’s transmitted by reference Sorry for this XD While the chars from the string are digits or a dot (.), add them to the dbl string In ASCII code, 48 is 0 ; 57 is 9 and 46 […]

## Ex: Evaluate Logarithmic Expressions without a Calculator – Common Log

We want to evaluate the given log expressions. Notice how for each log the base is not given, so we know these are common logs, meaning each log is base 10. To help us evaluate these log expressions, we’ll form a log equation by setting the expression equal to x, then we’ll write the log […]

## Master Solving Exponential equations without using a calculator

Welcome ladies and gentlemen. So what I’d like to do is show you how to solve an exponential equation using the one to one property. Now what’s special about the one to one property is majority of the times, we don’t have to use a calculator. All of these problems I’m going to solve, all […]

## Master Evaluating a logarithm without a calculator

Welcome ladies and gentlemen. And what I’d like to do is show you how to evaluate logarithms without using a calculator. Now, obviously for a majority of these– or actually for all of these, you could type them into your calculator using the change of base formula unless your calculator can do different bases. But […]
