How to solve (x+y)^1/2 - x^1/2?
Hi...
I need help...
How can you solve (x+y)^1/2 - x^1/2
I need it for a physics problem...
The problem is actually:
Delta v = ((ku^2/m)+2gh)^1/2 - (ku^2/m)^1/2
Can you help me please
I need to substitute delta V in an equation..
The equation currently is:
X=Delta v.(u/g).cos alpha.(k/m)^1/2

as far as I get you don't need to solve anything and your question is not that complicated as it looks like... you wanna substitute Delta V in the equation X=Delta v.(u/g).cos alpha.(k/m)^1/2 so you don't really need to solve anything. you just put the right side of the first equation ((ku^2/m)+2gh)^1/2 - (ku^2/m)^1/2 in the 2nd equation which makes it sth like the equation below:
X = [ ((ku^2/m)+2gh)^1/2 - (ku^2/m)^1/2 ] .(u/g). cos alpha . (k/m)^1/2
you can also calculate Delta V itself if you have values for k,u,m and h and then put the number in the 2nd equation... I hope I haven't misunderstood your question...
Good luck
