I'm having trouble with projectile motion, mainly with understanding which formulas do what. I understand some, others I do not.(adsbygoogle = window.adsbygoogle || []).push({});

Here are my formulas:

Vx= V cos theta-- I know this is to find x components

Vx= V sin theta-- I know this is to find y components

tan theta=R_{y}/R_{x}-- I know i use my resultant x and y components in these, but I don't know what tan theta is.

X=V_{0}t-- I do not understand this formula

Its mainly the V_{0}x and V_{0}y that I do not understand.

Thank you for your help.
