Quote:...that in my opinion should be built in to the HP Prime CAS from the beginning especially since there is a dedicated ∡ button!... Anders, that would be nice. Here is simplified version of my post to make it easier for HP Prime Free  Lite users to follow. Note: HOME view conversions of Polar to Rectangular and Rectangular to Polar are builtin. Alternate Approach below seems to be more stable. Implement CAS View versions: Press Define, type Name, and copy Function Name:P_to_R Function: CAS.exact(X*COS(Y))+CAS.exact(X*SIN(Y))*i Name: R_to_P Function: CAS.exact(CAS.collect(ABS(X+Y*i)))+"∡"+CAS.collect(ARG(X+Y*i)) <Edit 1  Dec 26, 2017> Alternate Approach  using CAS variables with local paramenters Copy each of these functions to the CAS command line and press enter (BEGIN, return, ENTER necessary for Windows Store version of Free  used for iOS Lite and Android Free as well): P_to_R(r,a):= BEGIN return (r*COS(a)+r*SIN(a)*i); END; R_to_P(x,y):= BEGIN return (CAS(collect(ABS(x+y*i)))+"∡"+CAS(collect(ARG(x+y*i)))); END; </Edit 1> Use your Define blue key with system copy and paste to set your User Functions to these values. Use the upper right hand icon to toggle between radian and degrees. Use <approximate> key if necessary. <arrow> key does not toggle CAS defined functions results.
