MATH QUESTION

I also want to know ε=ε=(ノ≧∇≦)ノ

I give this page to my friend who is in a math degrees and he said the same answer hhauaha I think is not too difficult

can you please explain like the process? i’d love to know how to derive that answer

there is something called photomath haha

...photomath doesn’t work with screens. also, photomath won’t tell me the theorem used so it’s essentially purposeless. but go off i guess.
