I need to brush up on how radians work real bad

what is pi/2 radians mean?

>>	Anonymous Sun May 31 20:49:32 2015 No.7299903 One fourth of a circle revolution or 90 degrees.

>>	Anonymous Mon Jun 1 19:38:46 2015 No.7301802 pi/2rad=180degree. now u can faggot nvert rad to degree and degree to rad using algebra

>>	Anonymous Mon Jun 1 19:39:55 2015 No.7301804 >>7301802 im sorry imeant 2pirad i think. i forget

>>	Anonymous Tue Jun 2 04:47:13 2015 No.7302489 >>7300056 nice never understood in school. only memorization and gtfo there to play games.

>>	Anonymous Tue Jun 2 09:37:47 2015 No.7302772 relate all your trig formulas to the unit circle and you'll have a very enjoyable time. think of it like the identity of a circle.

>>	Anonymous Tue Jun 2 09:46:55 2015 No.7302778 >>7301802 x rad = (x/pi)180 degrees = (180/pi)x degrees. y degrees = (y/180)pi rad = (pi/180)y rad. You basically just divide by some value of radians (or degrees), then multiply by the corresponding value in degrees (or radians).

>>	Anonymous Tue Jun 2 09:51:13 2015 No.7302784 >>7300562 They never explain what radians are. I didn't really even understand it until years later, when I'd finished my undergrad, and was teaching a kid and she asked "what exactly is a radian?" I thought for a second and finally understood it.

>>	Anonymous Tue Jun 2 10:21:44 2015 No.7302826 >>7302784 Radian means radius. Radians means radiuses. If you take the radius of a circule, the circumference will be 2pi times as long as the radius.

>>	Anonymous Tue Jun 2 10:33:05 2015 No.7302837 >>7302784 tons of math isnt explained in most schools. the general attitude is plug and chug. fuck understanding any of it. just be a human calculator.
