Inside Maths builds on the success of the series Maths 4 Real. Fran thinks Dave is turning into a couch potato so packs him off to a gym to do some exercise and send through some distance/time data for her to plot. Arriving at the gym, Dave is challenged by two students to a 200-metre sprint and a 1000-metre run on a running machine. Once the races have been run, Fran is able to plot the graphs and compare Dave's race with those of the students. It is clear that Dave is not much good. Maybe he will fare better on the rowing machine. But after a short energetic burst he gives up. Back in the studio Fran looks at the gradients of both Dave and the student rower, and shows that the student consistently rowed faster. Dave disagrees and asks Fran to check the race at around one minute in. At this point Dave's graph is a curve, so using tangents Fran is able to see that Dave was, for a short time, faster! Amazing.
