Many calculations are simpler when angles are measured in radians. One example is the series expansion (infinite sum) for the sine and cosine function. Another example is the formula that relates linear speed and angular speed in the case of a rotation.
Pi over 12 on a radian unit circle is a little more than a quarter of the circle. Radian units are an alternative to degrees.
180/pi, just over 57 degrees.
k radians = k*180/pi degrees. If the result is less than 0 degrees or greater than 360 degrees, then you can usually add or subtract 360 degrees as many times as you like so as to bring the answer into the required interval.
pi/12 = (pi/12)/(2pi) = 1/24 of a circle ( = 15 degrees).
Radian measure is preferred over degree measure in many mathematical contexts because it provides a direct relationship between angles and arc lengths in a circle, simplifying calculations in trigonometry and calculus. In particular, when using radians, the derivative of the sine and cosine functions is more straightforward, which is essential in calculus and applications involving periodic functions. Additionally, many mathematical formulas, such as those involving rotation and oscillation, are more naturally expressed in radians. Overall, radians facilitate a more seamless integration of geometry and analysis.
pi/6 = 30 degrees pi/6 = 0.523598775.... radians
Sine(pi/2) = 1 This is 'Radian' measure of an angle. pi/2 radians = 90 degrees. When you see something like 'Sine(pi/2)' make sure your calculator is in RADIAN mode. ' NOT degree mode.
1. Turn off your calculator 2. Flip it over 3. Get a pen or sharp pencil 4. Push "reset" 5. Flip over 6. Done
When addressing the person i would use dr, it's usually prefered over ms. When addressing the person i would use dr, it's usually prefered over ms.
No.
Larger brakes = shorter stopping distance.
Converting radian into degree: 5π/12 radian = {(5π x 180)/(12 x π)}o = 75o So, cos(5π/12) is equivalent to cos75o and cos 75o = 0.92175126972.
