Unformatted text preview: ∆ x /x = ∆ F/F Now back to the original equation V 3 = (F/ μ ) 1/2 lets rewrite this as V 3 = (x) 1/2 this falls under the power rule number 4 So ∆ v 3 /v 3 =[ (1/2)( ∆ x /x) 2 ] 1/2 Putting our F’s back in ∆ v 3 /v 3 =[ (1/2)( ∆ F /F) 2 ] 1/2 Then ∆ V 3 =V 3 *[ (1/2)( ∆ F /F) 2 ] 1/2 or I can expand it to ∆ V 3 =(F/ μ ) 1/2 [ (1/2)( ∆ F /F) 2 ] 1/2 Hope this helps!...
