I just need the graphs of the following equations.

1. y=1
2. y=x
3. y= x^2
4. y= 1/6(x^3)
5. y= 1/x^2
6. y= sin x
7. y = cos x
8. y = ln abs(x)
9. dy/dx = ½ x + 1
10. dy/dx = y
11. dy/dx = x-y
12. dy/dx = - x/y
13. draw the solution curves for the differential equation dy/dx = x+ y
At points (0,1) and (-3,0)
