Solving for p and q:
Given: [ x = \sqrt{a}(\sin u + \cos v) ] [ y = \sqrt{a}(\cos u - \sin v) ] [ z = 1 + \sin(u - v) ]
We need to express ( u ) and ( v ) in terms of ( x, y, z, ) and ( a ). Let’s start by squaring the equations for ( x ) and ( y ):
[ x^2 = a(\sin u + \cos v)^2 = a(\sin^2 u + 2\sin u\cos v + \cos^2 v) = a(1 + 2\sin u\cos v) ] [ y^2 = a(\cos u - \sin v)^2 = a(\cos^2 u - 2\cos u\sin v + \sin^2 v) = a(1 - 2\cos u\sin v) ]
Adding these two equations gives: [ x^2 + y^2 = 2a(1 + \sin(u - v)) = 2a(1 + z - 1) = 2az ]
This simplifies to: [ z = (x^2 + y^2)/(2a) ]
Now, let’s find an expression for ( p = (\tan u)/(\tan v) ):
Dividing the equation for ( x ) by the equation for ( y ), we get: [ p = (\tan u)/(\tan v) = (\sin u + \cos v)/(\cos u - sin v) = (x/\sqrt{a})/(y/\sqrt{a}) = x/y]
Similarly, let’s find an expression for ( q = (\cotan(u))/(\cotan(v))) :
Dividing the equation for ( x) by the equation for ( y) gives: [ q=(\cotan(u))/(\cotan(v))=(\cos(v)+\sin(u))/(-\sin(v)+\cos(u))=-(x/\sqrt{a})/(y/\sqrt{a})=-x/y=-p]
Therefore, p=-q.
Hence, the values of p and q are such that p=-q.
