read the help. the syntax for curve needs initial values for parameters or try implicit form or better conic and line
ie: conic(a(0),a(1),a(2),a(3),a(4)); line(b(1),b(3))

the ¿bug? needs a check your input message
If you input
intersect(a,b,3,3)
the CPU 100%, and no result.
maybe not a bug. but it really has something.
please check that file attached.
in that file, there is another bug:
in that file, there is another bug:
when you input:
(2cos(θ), 4sin(θ))
it is ok. but when you save and reopen, it is "undefined"
win10+Geogebra5.0.579d
newly i think (2cos(θ), 4sin(θ)) that returns X=(0,0)+(2cos(θ), 4sin(θ)) is not supported syntax
the correct syntax for parametric curves is curve(2cos(θ), 4sin(θ),θ,0,2 pi)
I think there is a bad interpretation with X=(1,2)+t (3,4) for lines and (2cos(θ);θ) for polar curves

it is possible Curve((2cos(θ), 4sin(θ)), θ, 0, 2π) also

thank you, mathmagic!
I knew that reason, I think that the application should has strict syntext，that will minimize ambiguity.
