Resolve Windows 10 related issues for your HP computers or printers by HP Windows 10 Support Center
Can I please have some assistance with the following question:
I am able to complete the question by hand by substituting z = x + iy.
This question, however, is only worth one mark and the hand calculations take too long.
Is it possible to quickly solve this question using the HP Prime Graphing calculator?
Go to Solution.
Maybe the quickest way is:
Be sure that your CAS settings are set to default.
Enter your equations in CAS, with z=x+i*y
CAS will convert them into real equations in x and y.
Open the Geometry app and use Plot Implicit. Paste the results from CAS.
The Geometry app is rather unstable though and can cause crashes.
For this reason I advice to turn the calculator off and on regularly to store your work so far into memory, so that it not gets lost in a crash.
I prefer the Advanced Graphing app, but the disadvantage is that you have to convert all lowercase x and y into uppercase.
That works really well 🙂
