Hey I'm part of matric 2024 and I'll be doing the investigation soon... Any tips on what to expect?

Thank you so much. Simple methods to find these identities if we forget. Please, have you a video to find easily Tg (A+B)?

Shouldn't the x-coordinates of P be negative?

[@SelaeloKutume]

That used to be my problem too but she clarified it 'because cos'a is negative therefore it will be (x ) because even it is negative too'

[@StheMgabhi]

So we don't need to apply the square roots when doing this question?
