The R Formulas

[@Autocaniball]

This baffles me completely I can understand the addition and double angle formulas easily but this is a complete step up

[@Chewy427]

that Pythagoras really caught me off guard and blew my mind lol

[@kookokie5945]

This was really helpful :)

[@possiblyunmatched1323]

why do you not make Rsin(alpha)=-6 but instead make it equal to 6?

[@zenab9931]

would you be able to re-order the playlists to fit the new maths a level spec? (e.g AS pure, AS stats and so forth)

[@q8yMontages]

Some ppl are still on the old spec tho

[@hackercop]

This was really helpful thanks

[@maisieramsey1124]

Why can't you just put alpha back into one of the two equations to find R? i.e. why is it necessary to do pythagoras?

[@xxslysinxx]

If u think its easier lol, pretty sure both methods work. Pythagoras is fast method too

thankyou sm i finally felt it is easy
