I'm not sure. I double checked and that is what is written, perhaps a typo? Maybe the Vm_dot in the given answer should be just plain Vm?Hi,
Just one question, why are they giving the solution to Vm_dot if they are going to give the entire solution in terms of Vm_dot and not just plain Vm ?
The first step is to ask if the proposed answer makes sense.
Hi there,The first step is to ask if the proposed answer makes sense.
We know that v is a real number, since both Re{z} and Im{z} are real numbers.
So is the claimed answer a real number? This would require that the arg of Vm_dot be equal to exactly -pi/4. But alpha is an arbitrary angle, so this is not the case.
Hence we know the answer is wrong.
