## Newton’s Approximation for Pi

In 1666 Newton found Pi to sixteen decimal places by evaluating the first twenty-two terms of an infinite sum. Celebrate Pi Day with your students by following in Newton's footsteps and doing the maths to derive his sum, or by evaluating many, many terms of the sum by hand, and getting an approximation for Pi.

## Parking Angles

In this video Matt is in Sydney where many parking bays are angled at 60 degrees. He explores which angle causes parking bays to take up least and most space on a road. Use our trigonometry activity so your students can do the same!
