Constant Angle Spacelike Surface in de Sitter Space S-1(3)

In this paper; using the angle between unit normal vector field of surfaces and a fixed spacelike axis in R-1(4), we develop two class of spacelike surface which are called constant timelike angle surfaces with timelike and spacelike axis in de Sitter space S-1(3). Moreover we give constant timelike angle tangent surfaces which are examples constant angle surfaces in de Sitter space S-1(3).
