The equation I was taught is:

y = tan(θ)x - ( g / 2vo²cos²θ ) where vo = initial velocity vector

This equation was derived from: x = VxoT -or- T = x / Vxo (T = time) and

y = VyoT - ½gt²

Please help me understand how to apply this formula correctly.

Thank you very much,

p.s. I know I didn't answer part three of the Template, however my question is more conceptual based rather than example. Pls don't delete
