I have an equation that looks like this

Is there any easy way to simplify this? It's almost a perfect square.

Well, you can put the quantity under the square root under common denominator v

_{0}so that you will cancel the v_{0}at the outside and will get [v_{0}^{2}-2gtv_{0}sinx+(gt)^{2}]^{1/2} - November 14th 2012, 06:02 PMskeeterRe: Simplify this function

For a projectile launched with velocity at angle , what is the magnitude of the velocity vector at time ?

Apply the pythagorean theorem and you'll end up where I am.

Unless I did something wrong. Stayed up till 2 AM doing this stuff. - November 14th 2012, 06:14 PMskeeterRe: Simplify this function
fix your equations ...

(note there is no ... velocity in the x-direction remains constant)

(first term does not have a ) - November 15th 2012, 01:44 PMjeremy5561Re: Simplify this function
sorry, am really tired. I did it correctly originally. Don't think it can be simplified further.
