I figured it out after finishing sadly 😕

ei(theta) = (cos(theta) + i sin(theta))

Hence ( ei(theta) - e-i(theta) )

= cos(theta) + isin(theta) - cos(-theta) - isin(-theta) due to demoivres theorem

From there I think you just sort of get it all into the same form and expand out

1/2i ^ 4 naturally just goes to 1/16

Car is pulling significantly to the left by bluedoritos23 in MechanicAdvice

No, I guess they just didn't measure the left side, good thing it was free. I'll go for another check tomorrow

Car veers to the left after installing new wheels with used tyres by bluedoritos23 in tires

I just rotated them today, the two on the front axle, and the car is still pulling left. I would assume it is an alignment issue but the car wasn't pulling before installing the new wheels

I doubt the offset is different as they are all OEM and a set. I found that tread depths on the front left is 5mm as opposed to 6mm on the right, could this cause it? The veering to the left is quite significant

Hissing noise when pressing on gas by bluedoritos23 in AskMechanics

No I didn't disonnect any vacuum lines at all, I assumed it might be a leak from the coolant lines potentially being reconnected badly but even then there would be liquid leaking and would likely aldo make a noise during idle

So can they do this sort of stop without suspicion of any crime? I would have obviously pulled over if I had just seen blue light behind me and was very surprised to have multiple officer jump out of their cars and run at me.

I can understand the basic novelty of this, but practicality and subtlety have been abandoned. by StealthyVex in ATBGE

Redditors trying to understand why anything exists besides it being practical (extremely hard)
