1. 315 degrees,-405 degres
Add 360 or -360 degree
2.e^(ln(x+1))=e^0
x+1=e^0
x=(e^0)-1
edit: e^0=1 I was on my phone earlier so x=0

I really admire math geniuses.. I see them like superheroes.. this Romanian girl I went to high school with was such a math wiz, numbers fall to her like wahyi while they bounce off of my grasp... I don't think I could pass my math classes without her help
