Homework Statement
Graph the surface in R3
Homework Equations
Spherical equation [tex]\rho[/tex] = 2asin([tex]\varphi[/tex])
The Attempt at a Solution
I think its just a sphere with a radius of 2

Homework Statement
Graph the solid whose given coordinates satisfy the inequalities
Homework Equations
a) 0 [tex]\leq[/tex] r [tex]\leq[/tex] 3, 0 [tex]\leq[/tex] [tex]\theta[/tex] [tex]\leq[/tex] [tex]\pi[/tex]/2, -1 [tex]\leq[/tex] z [tex]\leq[/tex] 2
b) 2r [tex]\leq[/tex] z [tex]\leq[/tex] 5 - 3r
The Attempt at a Solution
I figure these are cylinders because of variables used to describe the coordinates but besides that I'm having trouble know what to use the inequalities for

Homework Statement
Graph the solid whose given coordinates satisfy the inequalities
Homework Equations
a) 0 [tex]\leq[/tex] [tex]\rho[/tex] [tex]\leq[/tex] 1, 0 [tex]\leq[/tex] [tex]\theta[/tex] [tex]\leq[/tex] [tex]\pi[/tex]/2,
b) 0 [tex]\leq[/tex] [tex]\rho[/tex] [tex]\leq[/tex] 2/cos[tex]\varphi[/tex], 0 [tex]\leq[/tex] [tex]\varphi[/tex] [tex]\leq[/tex] [tex]\pi[/tex]/4
The Attempt at a Solution
Spheres, but same problem as with the others, I'm just not doing well at understanding how to use the inequalities to graph it
