Radian measure I know what a radian is Learning objectives 23/05/2019 I know what a radian is I can convert between radians and degrees

We can use the same scale on the x and the y axis and they are both in numbers. if we did this with the x axis in degrees, the graph would be well stretched out and the x axis is not really in numbers.

What is a radian?

to convert degrees to radians multiply by 𝜋 180 The second most thrilling experience in the universe is to be able to convert between radians and degrees to convert degrees to radians multiply by 𝜋 180 to convert radians to degrees multiply by 180 𝜋 this is because the total arc length is the circumference of the circle = 2𝜋𝑟 but arc length = θr where θ is the angle of the arc θ = 2𝜋 = 360°

to convert degrees to radians multiply by 𝜋 180 Convert 60° to radians. Leave you answer in terms of 𝜋. to convert radians to degrees multiply by 180 𝜋 Convert 3𝜋 4 radians to degrees
