Need help with both of these... Thanks

(a)
in cylindrical coordinates,
we have
x²=r²cos²
y²=r²sin²
and
z²=z²
our equation becomes
(r²cos²
)/4 + (r²sin²
)/9 + z²/(1/4)=1
where r²=x²+y²
and
= tan-1(y/x)
(b)
in spherical coordinates,
=> x²=²sin²
cos²
y²=²sin²
sin²
and
z²=²cos²
so our equation becomes
(²sin²
cos²
)/4
+ (
²sin²
sin²
)/9
+ (
²cos²
)/(1/4)
=1
where
²=
x²+y²+z²
=tan-1(y/x)
=tan-1
((√(x²+y²))/z)
