can you explain why that (sin(pi/2) -1)(tan(pi/2)+2) = 0, because i thought that undefined times zero is undefined and the calculator cannot figure it out.... i quite baffled tbh

Hard to explain since I used 4u to graph it. I've seen these situations like absolute values where if you put the value in the calculator, it reads limited answers but when you graph the solution, there are actually more answers. But since this is 2u, they would most likely accept B since 2u is so limited.

so its B then?
Hope not :p

for the sake of both us and people of similar mindset that they'll accept both, but that is most unlikely
