Hi,

Any help re-arranging the equation below would be greatly appreciated

The following equation needs re-arranging to work out alpha (a)

Phase max = 90 - (2 * tan-1 (sqrt a))

In the actual problem my phase max = 14.14 and I know that the value of alpha (a) should work out to be 0.6072

I need to be able to derive the equation above in an upcoming exam so any help would be appreciated

Thanks

Dave
