The equations for projectiles shouldn't just have theta, they should have sin(theta) or cos(theta).
As long as you have your calculator set in the right mode, either will work when you evaluate sin or cosine.
Example: Say you have a projectile launched at 30 degrees above horizontal. In order to find the y velocity, you will have to calculate sin(30) with you calculator in degree mode. If instead you called this angle pi/6 (the same angle, just in radians), you could enter sin(pi/6) in your calculator in radians mode and get the same answer.

How do you do coterminal angles with radian measure?
The same way as with degrees. All you have to know is how to convert degrees from radians and radians from degrees.... this is how you do it... radians= pi/180 degrees= 180/pi to get angles from degrees to radians you multiply the angle that is measured in degrees by pi/180. to get angles from radians to degrees you multiply the angle that is measured in radians by 180/pi. pi=3.14
What does a zero with a horizontal line through it mean?
It means a central angle measured in radians. ex. Convert 360 degrees radians. 180 degrees = pi radians so 360 degrees = pi radians/180 degrees = 360pi radians/180 = 2 pi radians
What is 2115 degrees in radians?
pi [radians] = 180 [degrees] 1 [degree] = pi/180 [radians] = 0.0174533 [radians] therefore, 2115 [degrees] = 2115 [degrees] * 0.0174533 [radians/degree] = 36.9 [radians]
Degrees to radians?
Degrees x 0.01745 = radians
What is the sine of 50 degrees in radians?
The sine of an angle returns a dimensionless ratio, not an angle, which can be measured in either degrees or radians (or gradians, if you want to get technical). Sines and other trigonometric functions except angles as input to return this ratio. The sine of 50 degrees is .766044443119. The sine of 50 radians is -.262374853704.
How do you draw a triangle with a right angle that's 4cm?
Angles are measured in degrees or in radians, but not in centimeters.Angles are measured in degrees or in radians, but not in centimeters.Angles are measured in degrees or in radians, but not in centimeters.Angles are measured in degrees or in radians, but not in centimeters.
What degree is pi when measured in radians?
pi radians is 180 degrees.

The units in which angles are measured?
Degrees or Radians
What are angles measured in radians equal to?
The angles measured in radians are about 57.3 degrees. A measurement of an angle in radians is equal to the length of its corresponding arc in the circle.
What are the units for angular displacement?
Angular displacement is measured in radians (rad) or degrees (°).
What does a zero with a horizontal line through it mean?
It means a central angle measured in radians. ex. Convert 360 degrees radians. 180 degrees = pi radians so 360 degrees = pi radians/180 degrees = 360pi radians/180 = 2 pi radians
What is the value of an angle?
Angles are usually measured in degrees. They can also be measured in radians.
In calculus what does 10 degrees equal?
In calculus, angles are usually measured in radians. To convert degrees to radians, multiply the number of degrees by pi/180.
What is degree in trigonometry?
Angles are measured either in degrees or in radians.
Unit of measure of an angle?
Usually an angle is measured in degrees or radians.
What are the units of measuring angles?
Angles can be measured in degrees, radians and revolutions.
