Move the sliders to change the complex numbers

=

a = 2 (slider from -5 to 5, step 1)
b = 3 (slider from -5 to 5, step 1)
c = 4 (slider from -5 to 5, step 1)
d = 1 (slider from -5 to 5, step 1)
i = (0, 1)
O = Intersect(yAxis, xAxis)
u = Vector(O, (c, d))
v = Vector(O, (a, b))
z_1 = Point(O, v)
z_{2} = Point(O, u)
z: u + v
g = Segment(O, z_1)
h = Segment(O, z_{2})
z_3 = Point(z)
e = Segment(z_{2}, z_3)
f = Segment(z_1, z_3)
j = Segment(O, z_3)
text4: z_3 + ""
text2: "z_{2} = " + "  c  +  di   =   " + c + "   +   " + d + "i"
text1: "z_{1} = " + "  a  +   bi  =  " + a + "   +   " + b + "i"
text3: "z_{3}    =     z_{1} + z_{2} =" + (LaTeX[z_3]) + ""
