This is a video from everystepcalculus.com demonstrating how my programs work and I TI 89 titanium calculator and other calculators and a TI system for calculus and physics problems okay implicit differentiation my programs work on that and let’s get started yep for a second offer to put the letters i ndex in here and you have for itself but it but the a you can close parentheses press Enter into my menu I’m already at implicit differentiation you can screw whatever you want here press Enter and we’re gonna enter function you have to Press alpha before you enter anything in these and felines here’s member that alpha and let’s go 5 time X by minus 3 X squared why bus for six. I always show you what you’ve entered you can change it if you want notice that this is people’s six let it take to get a problem where there’s the this for a while the on this side will be here well you need to transpose it over to the other side so this would be a minus 4 y-o-u 6 -4 why so make sure you just have a zero or the constant right side 280 trickier s. I say it’s okay to press one here and you gonna take DD except every term and that function which I’m doing here show you write this on your paper right here ever gonna take the first term and you notice that is going to be the product because you’re multiplying functions times why X years so now I show you the steps for the product rule but you can go quickly if you practice and greatly answer which is this answer here and it separates the way TX terms into ones spot for the ordinary terms and the next term is another product rules so show you write that down to be interested here’s the answer and the you idea except for it four times why equals this you a geek and you a txt 660 said make it zero on the right side and of course the period accustomed 0 so we’ve grouped all the ordinary terms and that the way the xterm and equals zero you gonna transpose this now over to the right side because here change the signs the course does that automatically years the answer the way DX equals this and this let’s do it at a let’s evaluate a point as always fun. Press alpha to pointed to alpha now I value it at this point here again I show you you made a mistake and you’re gonna like these numbers and this is for the X’s in the y values rate here all entered in the year as the calculation 63 over to in a corset handed -1 30 arcane 31-point by is here’s the actual degrees ovett with you meet the this is rise over run maybe go up 63 points on the Y axes and over to the right and the xx’s draw a line from there down through the origin and that graph you you found the slope that my SAT point2 agrees. Pretty neat. everystepcalculus.com. Go to my site by my programs and pass calculus.
