4. Radians! If we convert degrees into radian measure, then we are allowed to treat trigonometric functions as functions with domains of real numbers rather than angles! What is a radian? Okay, so radian is an angle with vertex at the center of a circle that intercepts an arc on the circle equal in length to the radius of the circle

Radians are commonly given in terms of $\pi$ to avoid dealing with decimals in calculations. In most books, the abbreviation rad is not provided, but the reader has to know that when talking about an angle that is given in terms of $\pi$, the units are automatically radians. Some basic angles in radians: $360^{\circ} = 2\pi\ rad 2 Radians to Quadrants = 1.2732: 80 Radians to Quadrants = 50.9296: 3 Radians to Quadrants = 1.9099: 90 Radians to Quadrants = 57.2958: 4 Radians to Quadrants = 2.5465: 100 Radians to Quadrants = 63.662: 5 Radians to Quadrants = 3.1831: 200 Radians to Quadrants = 127.324: 6 Radians to Quadrants = 3.8197: 300 Radians to Quadrants = 190.985 Exact algebraic expressions for trigonometric values are sometimes useful, mainly for simplifying solutions into radical forms which allow further simplification.. All trigonometric numbers - sines or cosines of rational multiples of 360° - are algebraic numbers (solutions of polynomial equations with integer coefficients); moreover they may be expressed in terms of radicals of complex. Remember that the formula for arc measure is: s / r, or 4 / 5. Now, let's convert 4 / 5 radians to degrees by multiplying by 180 / pi. (4 / 5)(180 / pi) = 45.837, or approximately 46 degrees. As 46 degrees is about 1/8 of 360 degrees, the arc should be about 1/8 of a circle, as shown in our example Consider what radians are. A complete circle is said to have #2pi# radians (if anyone asks why then say that it's made to fit the system of unit circles, circumference #c=2pir# with #r=# unit means #c=2pi# making trigonometric equations easier). Now, a complete circle is also #360^o#.. So that means, #360^o=2pi^cl# I'm using a #l# here because we don't know how exactly they're related, but. Now let's take a look at an example of calculating the arc length when the angle is given in radians. or this example we first need to measure the angle. Let's assume we get a measurement of 2.5 radians. First, we need to convert this into degrees. 1 radian is equal to 59.27 degress so 2.5*59.27=143.29. Next we need to measure the radiu Assuming you mean in terms of Pi radians, I guess you're looking for x*Pi = -0.983, which is straightforward algebra. This gives you about -0.313Pi. Feb 20, 201 It hasn't, really. Radians are based on π (a circle is 2 π radians), so what you really did was replace n ° 360 ° with θ 2 π. When θ 2 π is used in our original formula, it simplifies to the elegant (θ 2) × r 2. Area of a Sector of a Circle Examples. You have a personal pan pizza with a diameter of 30 c m Radians is always represented in terms of pi, where the value of pi is equal to 22/7 or 3.14. A degree has its sub-parts also, stated as minutes and seconds. This conversion is the major part of Trigonometry applications. Degrees x π/180 = Radians. Radians × 180/π = Degrees Converting Between Radians and Degrees. Each of radians and degrees has its place. If you're describing directions to me, I'd really rather you said, Turn sixty degrees to the right when you pass the orange mailbox, rather than, Turn (1/3)π radians at that point. But if I need to find the area of a sector of a circle, I'd rather you gave. Pi (π)Draw a circle with a diameter (all the way across the circle) of 1.
