Hey Giraffer. Didn't see this 'til now. Glad it helped. I'd like to take credit for thinking up the idea, but I'm sure one of my obnoxious math teachers (which I am now) taught me a million years ago. Just passing on the love! Good luck!
1. Make new line of y= value u want 2. Find intersection by doing 2nd calc and intersection 3. Navigate to intersecting points and the bottom will tell u what points ur at
Nothing wrong with your clip that helped me with this, but what were TI thinking? I mean, on my Casio I draw the graph push G-solve > X-cal and type in the wanted Y value and it search for it even if its outside of the visible graph.
I completely understand. I find if my students are smart enough to figure their way through the archaic landscape of the Ti interface they'll generally do just fine in math... and life. :)
@@petergorkiewicz4995 I like my TI-83+ but it's that it is a lot of jumping around between menus. Guess the newer once are different from the older too?
What if the intersection is way off screen and you don't know what to set the window to? Intersect only works if the intersection is off screen. For example, I need to find the x value that gives a y value of .5 in the function y=(.99987)^x. I can zoom out for days until the intersection is on screen, but I was hoping for a simpler solution.
Hey Patrick. 1970's technology isn't amazing with simple user interface. :) Try ZOOM --> 6:Fit. The calculator will try to fit interesting points, like zeroes and intersections, into the screen. Doesn't always work, but worth a shot if you have to hunt. Good luck driving that thing.
This is Ti Emulator, I'm using Mac. It was free during COVID for a while. Not sure at the moment. My school buys a license, so that's what I'm working with. Good luck!
I spent an hour looking for the way to do this, never thought of it was plotting another line with the y value! Thank you!
Glad it helped, my long-necked friend. Good luck with those intersections. -G

i almost cried because I spent so long working on a question and using this i found the answer in under 30 seconds. thank you for making this
Nifty little trick, hey? Glad it helped! Math is hard for everyone; we nerds have to stick together! Now go shred some problems!
This was exactly what I needed to check my decay formula. The second line idea is very clever + useful. Thank you.
I’m studying for my AP Calc test right now. I can’t tell you how helpful this video was. Thank you so much!
THANKS PETER, NEEDED THIS FOR MY CALC BC FINAL. YOU ARE A GEM.
Thanks got a quadratic function exam tomorrow. Really helps!
Glad it helped Aidan. Good luck on your exam!
Thank you! You’re a literal blessing.
Lifesaver. Also, it's hilarious I'm looking for 5.
1. Make new line of y= value u want
2. Find intersection by doing 2nd calc and intersection
3. Navigate to intersecting points and the bottom will tell u what points ur at
THANK YOU!! calc test saved!!
You’re a life saver bro
YOU ARE THE BEST. THANK YOU
Thank you, this is really helpful!
Ingenious, thank you so much!
You are amazing thank you !
THANK YOU. YOU SAVED MY FUCKING LIFE! I HAVE A TEST IN A WHILE. OKAY BYE
very nice trick, thank you
Thank you so much for this
Good trick!
This was very helpful, thank you
So helpful!
Thanks so much!! This was really helpful :)
Glad to help! We nerds have to stick together!
You saved me a lot if heartache. I will pay pal you a buck for the helpful video if you have pp
Ha! No need my friend. Glad it helped; pay it forward. -G
@@petergorkiewicz4995deal, you're a hero!
Thank you!! i was confuzzzzueld
Glad it helped! I hope you're appropriately uncofuzzzueld.

THANK YOU
But how do you find the x value when you have Y

I tried this and it says "ERR: NO SIGN CHNG"
what a goat
thank you so much!!
No worries Hanna. Happy it helped.
But what if the y value goes outside the graph and we can't see it on screen?
Use the WINDOW key at the top and increase your YMAX value. You can also try ZOOM ---> ZOOMFIT. Hope that helps. -G
Peter Gorkiewicz thank you
u could change the windows settings
BOI THANK U
What is the name of that program?
