Correct?

Is the answer to this equation correct? I'm unsure if it should 2g in the denominator of the answer. I think it should be just g.

 

(U sinX)^2/g - (U sinX)^2/2g

 

 

= (U sinX)^2/2g

 

(The g and the 2g are the denominator of (U sinX)^2 respectivley)

That's right. In order to subtract the two fractions, you first have to find a common denominator. Since the common denominator would be 2g, that is the denominator in the answer as well.

Thanks for that. I didn't look on them as being fractions :doh:
