For example, one revolution for our exemplary α is not enough to have both a positive and negative coterminal angle – we'll get two positive ones, 1040 ° 1040\degree 1040° and 1760 ° 1760\degree 1760°. The number or revolutions must be large enough to change the sign when adding/subtracting. For our previously chosen angle, α = 1400 ° \alpha = 1400\degree α = 1400°, let's add and subtract 10 10 10 revolutions (or 100 100 100, why not): Other negative coterminal angles are − 40 ° -40\degree − 40°, − 400 ° -400\degree − 400°, − 760 ° -760\degree − 760°.Īlso, you can simply add and subtract a number of revolutions if all you need is any positive and negative coterminal angle. ( 2 π 2\pi 2 π, 4 π 4\pi 4 π, 6 π 6\pi 6 π.), to obtain positive or negative coterminal angles to your given angle.įor example, if α = 1400 ° \alpha = 1400\degree α = 1400°, then the coterminal angle in the [ 0, 360 ° ) [0,360\degree) [ 0, 360° ) range is 320 ° 320\degree 320° – which is already one example of a positive coterminal angle. One method is to find the coterminal angle in the 0 ° 0\degree 0° and 360 ° 360\degree 360° range (or [ 0, 2 π ) [0,2\pi) [ 0, 2 π ) range), as we did in the previous paragraph (if your angle is already in that range, you don't need to do this step).

This year on 420, we are joining with many others to promote access to safe, legal, and natural cannabis products as many Americans believe that cannabis products can contribute towards a better quality of life.If you want to find a few positive and negative coterminal angles, you need to subtract or add a number of complete circles. While the Controlled Substances Act’s categorization of marijuana means it cannot be sold under federal law, the use of marijuana for medicinal purposes is legal in 36 states (at the time of writing), with an increasing number also legalizing recreational use too. While they left empty-handed that day, 420 became their thing and the term began to spread among their friends.įast forward half a century, the holiday has taken on a more purpose-driven tone, providing a platform for scientists, medical professionals, politicians, and cannabis consumers to discuss the medicinal benefits of the plant. Map in hand, they met at 4:20 pm and eagerly tried to locate the crop.
420 POSITION FULL
A group of students, known as the “Waldos,” because they used to hang out by a wall, came into possession of a map that they thought would take them to a field full of marijuana. The most concrete evidence of the holiday’s origins, however, can be traced back to San Rafael high school in Marin County, California. Another theory tries to attribute the date to a Bob Dylan song.

420 POSITION CODE
One popular rumor is that “420” is the code police officers use to signal to each other that marijuana smoking is taking place.

You can be forgiven for thinking 420 has more origin stories than the Marvel Universe.
