Find vertical tangent line calculator

It is fun and easy to use the camera is a little blurry when you first scan it but then it auto focuses, it hrlps you when you are stuck on your math homework, it is by far the best app I have used, love that I can take a picture of the problem and it solve it for me, thank you for this amazing, edicational and helpful app.

This is a great app I am a freshman at high school and it is helping me get correct answers on all of my tests and there is a variety of options to choose. It's good, 10/10 awesome app, when ever I get it wrong, it corrects me, it is a helpful tool for leaning and calculating difficult maths problems.

This app is so very helpful, i highly recommend this app, I used mathphoto and math app is WAY better especially if you're doing higher level math. Just wish the camera would read better. If you can't get the app there is one online you can search it up by using it's name.
