This is a video from EveryStepCalculus.com demonstrating how my programs work on a TI-89 calculator and other calculators in the TI system for physics and calculus problems. I’m going to differentiate a log to another base uhm and let’s get started for my menu you have to press second alpha and put i n d e x letters in here and then press alpha and to put the eight and the open and closed parenthesis press enter and you’re into my menu. I’m going to scroll down to ah this time I’m going to scroll up if you go up here you can go to the bottom of the menu here where it’s all alphabetical and were going to go up here to log problems here were going to differentiate so were going to press six can scroll down with the cursor or press six, I’m going to press six and I’m going to choose number two to do log to the base a and we’re going to enter our function you have to press alpha before you enter anything into these entry lines in this case were going to have to press alpha were going to have to press then second alpha that becomes black here in this little bottom part of the screen so you can put letters in because we need to there is no fuction to put log so we need to do that log and then were going to press ah alpha to put to the base let’s put base five and then we have to add the parenthesis and put in our function ah six times x squared. I always show what you’ve entered you can change it if you want so were doing log of base five to this function you write all this down on your paper exactly as you see it
f of x is six x squared and the a is five that’s the base here’s the formula y prime equals the one divided by the quantity f of x times the log of a and here’s your answer ahh pretty simple pretty neat, huh? everystepcalculus.com. Go to my site buy my programs and pass calculus.
