how to prove the 180 is a solution T formula (1 Viewer)

You know. You need to prove that 180 is a solution when using t formula. I need to know that. PLease explain how

Thanks

no need to prove, just consider the case and if its true when subbing it into orginal eq then that is a solution

Oh I see. Just sub 180 into the original equation and check for zero. Makes sense thanks

Also like remember to do it when a few specific cases I forgot but it’s like when the t cancels out or like when cos is opposite to the something something
