Finding p and q.

 

 

MANI addagarla

Find p and q,ifx=√a(sinu+cosv), y=√a(cosu−sinv), z=1+sin(u−v)

 

To find p and q, we need to express x, y, and z in terms of p and q.

 

We have:

 

x = √a(sinu + cosv) = √a(sin(p + q) + cos(p - q))

 

= √a(sin p cos q + cos p sin q + cos p cos q - sin p sin q)

 

= √a[(sin p cos q + cos p sin q) + (cos p cos q - sin p sin q)]

 

= √a(sin(p+q) + cos(p+q))

 

Therefore, we have:

 

sin(p+q) = sinu + cosv

 

cos(p+q) = cosu - sinv

 

Squaring both equations and adding them, we get:

 

sin^2(p+q) + cos^2(p+q) = (sinu + cosv)^2 + (cosu - sinv)^2

 

1 = 2 + 2sinucosv - 2sinvcosu

 

sinucosv + cosusinv = 1/2

 

Multiplying the first equation by cos(p+q) and the second equation by sin(p+q), we get:

 

x cos(p+q) = √a(sinu + cosv)(cosu - sinv) = √a(sinv cosu + sinu cosv) = yp

 

y sin(p+q) = √a(cosu - sinv)(sinu + cosv) = √a(cosu sinv - sinu cosv) = -xq

 

Adding these two equations, we get:

 

xp - yq = √a(sinv cosu + sinu cosv)cos(p+q) - √a(cosu sinv - sinu cosv)sin(p+q)

 

= √a[sin(p+q)cosu + sin(p+q)cosv + cos(p+q)sinu - cos(p+q)sinv]

 

= √a[sin(u+v)cos(p+q) + cos(u-v)sin(p+q)]

 

= √a[sin(p+q)(cosu cosv + sinu sinv) + sin(p+q)(sinu cosv - cosu sinv)]

 

= √a[sin(p+q)cos(u-v) + cos(p+q)sin(u+v)]

 

= √a[sin(p+q)z + cos(p+q)y]

 

Thus, we have:

 

xp - yq = √a[sin(p+q)z + cos(p+q)y]

 

Solving for p and q may be difficult without additional information or constraints.
