#Calcpad extension free
While the FREE version does all the above, teachers with a Task Tracker subscription can take things a step further. They can modify our pre-made problem sets, write their own problems with our easy-to-use Problem Builder, and use the Calculator Pad to design their own program that expresses their emphasis on the use of mathematics in Physics.

Sometimes, when we see the ancient marvels of engineering, we wonder: “How they designed this without computers”? And the answer is: “with knowledge, inspiration and hard work”. However, being almost irreplaceable, computers makes us more and more adjective. Our brains become lazy and we are losing some knowledge and skills. This is an equation of type f( x) = 0 and we can solve numerically it using the Newton’s method: Square rootīy squaring both sides and moving a to the left side, we obtain the following equation: It is so easy and elegant, so I will share it here for the sake of the good old math science.
It is interesting that just after 4 iterations, the Newton’s method finds 16 correct significant digits which is the limit precision for most computers. We also calculated the root by three different methods which give the same result. This entry was posted in Math and tagged Cubic root, Math, Newton's method, Root on Apby Calcpad. Along with a whole lot of easy running I’ve done a few faster runs in the Infinity Run, including a half marathon in around 1hr 26min and 8km at 3min 45sec/km pace followed by a few strides. The shoe has felt great throughout, and I’d only hesitate to grab it for track workouts, sessions at race pace and actual races. Even then it would be a solid marathon or half marathon race shoe for many runners – those who aren’t ready to buy a specialist racing shoe like the Nike Vaporfly or Adidas Adios 4. I especially enjoyed using the shoe for my run commutes, which have frequently been done on cold, dark winter mornings in the rain – the kind of run you generally just want to be over, but getting to know the Infinity Run made them a lot more fun. The Infinity Run is also designed to help reduce injuries. According to Holts, the shoe is the first step in what will be a key focus for Nike in the future. “Our aim was to address the evergreen needs of runners of all levels,” he says. “One need is staying healthy and injury-free. This is our first step in that direction – in trying to reduce running-related injuries not just through products, but also guidance through training that we can offer though the NRC app. We see this as an opportunity to really focus on a benefit that can help improve the running experience of all runners.” “Injury is something that has plagued runners of all levels for decades, and really the industry hasn’t made big strides in terms of reducing those rates in the past 30 or 40 years, including ourselves at Nike. That’s evident from the Infinity Run, which has more cushioning than past React shoes – 24% extra foam – and a wide base at the heel and forefoot to make it more stable.

The wider forefoot does also have an extra benefit in that it means the Flyknit upper doesn’t cramp your toes at all, which has been a complaint with past Nike Flyknit shoes including the Epic React. The Infinity Run is very roomy, to the point where people with narrow feet might find it a little too spacious, but I found it only increased the comfort of the shoe. I’d say that reducing your risk of injury is far more down to getting your training structure right than choosing the right shoe, so the guidance from the NRC app is probably the crucial bit here. "A lot of it will come from training variation,” Holts says.
