Plugging the angle value, in degrees, in the previous formula, we get α rad = π × 126 /180 = π × 126÷18/180÷18 = 7π/10 radian, when reduced to lowest terms Note 7π/10 rad can be expressed as real number or as a decimal as 07π rad = radiansSine of 45 degrees is square root of 2 over 2 Sine of 45 is the square root of 2 over 2 We have a minus there so minus the square root of 2 over 2 And then cosine is just square root of 2 over 2 So we multiply it times our vector x So this matrix, if we multiply it times any vector x, literally So if we have some coordinates right hereThis activity was created by a Quia Web subscriber Learn more about Quia

In a half circle there are π radians, which is also 180° π radians = 180° So 1 radian = 180°/π = ° (approximately) To go from radians to degrees multiply by 180, divide by π To go from degrees to radians multiply by π, divide by 180 Here is a table of equivalent values DegreesRadians = (90° × π)/180° = π/2 = 0785 rad Thus, a right angle is expressed as π/2 radians What Are 60 Degrees Converted to Radians?Start studying Radians>Degrees/Degrees>Radians Learn vocabulary, terms, and more with flashcards, games, and other study tools
How to convert degrees to radians? The 360 represents the 360 degrees in a circle Using the arc length of 3 inches from the previous slide, and a radius of 45 inches from slide No 2, you would have Sector Angle = 3 inches x 360 degrees / 2(314) * 45 inches Sector Angle = 960 / 26 Sector Angle = 3397 degrees, which rounds to 34 degrees (out of a total of 360 degrees)2 Since one counterclockwise revolution forms an angle of 360° or 2π radians, the equations for converting between degrees and radians are 360 2 1 π °= radians = 180 π radians and 1 radian = 2π 360 degrees = π 180 degrees Problems 3 What is the radian measure of 108° angle?

So 90° = π / 2 radians We usually suppress the unit of measurement "radians" since it is understood if no other units for angles is specified Also, since an angle in radians is defined as the ratio of two lengths, L/r, it is dimensionlessScientific Calculator This is a very powerful Scientific Calculator You can use it like a normal calculator, or you can type formulas like (37^2)*2In Figure 6, notice that if one of the acute angles is labeled as θ, θ, then the other acute angle must be labeled (π 2 − θ) (π 2 − θ) Notice also that sin θ = cos (π 2 − θ), sin θ = cos (π 2 − θ), which is opposite over hypotenuse
