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.
Why does a car's engine get hot? Why does a car's engine get hot when it is running? A car's engine is not efficient. The engine works by converting chemical energy in the form of fuel to the mechanical energy (work) that drives the wheels and makes the car move. But only about 20 to 30 percent of the chemical energy is actually converted to mechanical energy.
