Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

why is it that there is negative in a degrees? how will we measure it?

Degrees are rational ( ex 180 ) , but radians are irrational ( because Pi is irrational ). So how can 180 equal to Pi ??? Because a rational number can never be an irrational number

what if i have 1.9 radians, and i need to calculate the length of an arc
@kaidenkraft1515
@kaidenkraft1515 6 ай бұрын
Sal has another video on this topic, but if you had an angle of 1 radian, the arc length is equal to the radius of the circle -- That's how a radian is defined Therefore, you simply multiply the radius by the radians to get the arc length. [ 1.9r == arc ]

*Uno Reverse card to 3 yrs ago XD* Pi.rad = 180 Rad = 180/pi 7.25rad = 7.25*180/pi 7.25 rad = 415.394

you just need to know the fact that pi radian is 180 degrees for ex : 5pi / 3 = 5.180/3
