Question

How many degrees are in 3pi/2 radians?

Answer 1

A full circle is 360 degrees.
If you take the Unit circle, the circumference is 2*pi*r=2*pi*1=2pi.
Because the radian is the same unit as the length of the unit circle, there are also 2pi radians in a full circle.

So remember: 360 degrees = 2pi radians.

Now can you see the number of degrees in 3pi/2 (= 3/2*pi) radians?

Answer 2

thx

Answer 3

so whats the answer

Answer 4

pi = 180

3pi/2
= 3(180)/2
= 3(90)
= ?

Answer 5

still confusion?

Answer 6

You can't make it any more obvious than that.

Answer 7

ya i get it thx

Answer 8

So...what is it then?

Answer 9

270

Answer 10

What is the exact value of cos 45° as found on the unit circle?

Answer 11

I'm only going to show you this once...I hope you understand it

Answer 12

k

Answer 13

\[\sin(0,30,45,60,90) = \frac{\sqrt{0,1,2,3,4}}{2}\]

\[\cos(0,30,45,60,90) = \frac{\sqrt{4,3,2,1,0}}{2}\]
