The cosecant is the reciprocal of the sine. The cotangent is the reciprocal of the tangent. The secant is the reciprocal of the cosine. If you have sin x = 3/5, then csc x = 5/3.
The actual fuel used by the IRL is a blend of about 98 percent ethanol and 2 percent denaturant. The exact composition includes a small amount of high-octane racing fuel. The fuel for today's Indy cars has an octane rating of 113, compared with methanol's 107. This means a significant reduction in pre-ignition, or knocking and pinging. In addition, many of the people who handle the fuel, say it smells like tequila.
If the car dies as soon as the donor vehicle is detached, you most likely need a new alternator. A loss of fuel is a very common cause of a carâs engine stopping and not re-starting.
