# Multidimensional Plots in Julia

We will plot the set of points $$(x, y, z)$$ where $$z : \mathbb{R}\times\mathbb{R} \rightarrow \mathbb{R}$$ such that,

$z(x, y) = y\cdot\sin{x^3} + x\cdot\cos{y^2} \,.$
z(x, y) = y*sin(x^3)+x*cos(y^2)
plot(-pi:0.01:pi, -1:0.01:1, z, st=:surface, camera=(-30, 15))

We can also plot the contours for another view of the set.

z(x, y) = y*sin(x^3)+x*cos(y^2)
plot(-1:0.01:1, -1:0.01:1, z, st=:contour)
