Then press ESC to exit the Tangent Line command. You would then click on the polar curve once to select the curve and a second time to place the tangent line.
Then drop a tangent line on the polar curve (menu –> 8:Geometry –> 1:Points&Lines –> 7:Tangent). So, finding an equation of a tangent line to the polar curve at the point of interest should find the desired result.Ĭreate a graphing window and enter your polar equation (menu –> 3:Graph Entry –> 4:Polar). Remember that a derivative at a point is the slope of the tangent line to the curve at that point. For an example, I’ll use and assume you want the derivative at. The CAS approach is much more accurate, especially in locations where the value of the derivative changes quickly, but I don’t think it’s necessarily more intuitive unless you’re comfortable using CAS commands. There are two ways I imagined to get the polar derivative value, one graphically and the other CAS-powered.

NO ACTUAL GRAPHING CALCULATOR INCLUDED.The following question about how to compute derivatives of polar functions was posted on the College Board’s AP Calculus Community bulletin board today.įrom what I can tell, there are no direct ways to get derivative values for polar functions.

We also have apps for the calculators: TI-Nspire CX (and CAS), TI-84 Plus, TI-84 Plus CE, CASIO fx-9860GlI
As an alternative, the app shows you mixed math problems of all topics. You can practice math problems of a single topic (e.g., Zeros of a Function) or random math problems of Differential Calculus for example. Practice with over 60 math problems and solutions. Permutations, Combinations & Factorials. You only have to take a look at the app and know how to do! Your teacher will be grateful as well because he doesn't have to walk around the classroom until everyone's calculator shows the right solution. It covers all you need to know for the ACT and SAT. The app is also ideal for exam preparation as you often don't remember all instructions of the calculator after several months. The app guides you with easy to understand explanations and offers the ability to show animations. You only have to swipe right to get the next screenshot which looks similar to your calculator display! Every topic shows a detailed instruction through screenshots of the original graphing calculator TI-84 Plus which explain how to use the calculator. Not yet convinced? Here's how you would benefit from this app: More than 60 math problems with solutions to practice your skills!. 
Additionally, there are helpful descriptions of further knowledge and useful tips. You can swipe through screenshots of the original graphing calculator which show every step you have to do (220 screenshots in total) or watch small animations to see how it works on the TI-84!. It covers the chapter:s First Steps, Graphing Basics, Differential Calculus, Solve Equations, Integral Calculus, Matrices and Statistics & Probability. The app shows the exact key press sequence for 46 topics. Also suited for TI-83 Plus, TI-84 Plus Silver Edition, TI-84 Plus C. ABSOLUTE VALUE ON TI NSPIRE CX MANUAL
This manual shows all important functions of the graphing calculator TI-84 Plus, which are very useful for high school and college. The TI-84 Graphing Calculator Manual app is ranked TOP 25 Education USA! It includes an actual TI-84 Plus CE calculator, the manual of the calculator and more.
