Complex to Polar Function Problem/Solution is unclear

[xinoehp512]

For most of the outputs, how to answer the problem is clear from the way the problem is written. With the complex to polar form generator, however, that is not the case. From the name of the generator, it seems that the goal is for the problem to be a complex number of the form a+bi, for which the solution would be the equivalent complex number in polar form: r(cos(theta)+i*sin(theta)).
