I would like to calculate the area under a curve to do integration without defining a function such as in integrate(). My data looks as this I plotted plot(strike, volatility) to look at the volatility smile. Is there a way to integrate this plotted "curve"?Each track system also has wider curves though a greater variety of the wider curve sizes lies in the O Gauge systems. O-27 features 42" and 54" diameter curves while O Gauge includes those sizes as well as 72", 82", 96" and in some systems even wider curves. Locomotives designed to operate on a 42" curve cannot operate on 31" or 27".

1 day ago · A car with a mass of 1,200 kilograms is moving around a circular curve at a uniform velocity of 20 meters per second. The centripetal force on the car is 6,000 newtons. The radius of the curve is 80 meters. Solution: cf = mv^2/r; 6000 = 1200*400/r; r = 80 meters. Curves of larger than minimum radii require lower amounts of superelevation, therefore providing a comfortable ride over a wider range of speeds. Alignments consisting of curves that are all at or approaching minimum values are an indication of a poor quality design.
