/sci/ - Science & Math

hello /sci/, looking to find my gross pay from my net pay for my tax( e.g what 4530 was before 15% was taken out). all my attempts to calculate it feel wrong. Here's to hoping you guys will help.

uh, i hit a math problem thats kinda confusing me about what angle to use. im not sure weather or not to use 270 degrees or just negative 90.

"a plane is flying through a huricanes eye at 3500 feet parrell to the ground, weather probes are dropped at an initial velocity of 300 MPH. write the parametric equation which plots out the probes paths."

do i just graph out a straight line?

>that feel when completely bombing a final
I don't expect /sci/ to empathize, but I'd rather bitch about it here than in real life. It was in Physics II by the way..
