Formula for S=rθS=rθ The picture below illustrates the relationship between the radius, and the central angle in radians. The formula is S=rθS=rθ where s represents the arc length, S=rθS=rθ represents the central angle in radians and r is the length of the radius. Demonstrati...
Assuming the broadband noise (A7) is dominating the performance, we calculate the Phase Jitter in radians [root mean square (RMS)] as: Phasejitter=2x10A10 or (A = –77 dBc) ~2 × 10−4 for our example, which translates to an RMS jitter time value in seconds using: Tjitter=Phaseji...
Some typical refractive indices for yellow light (wavelength equal to 589 nanometres [10−9metre]) are the following:air, 1.0003;water, 1.333;crown glass, 1.517;denseflint glass, 1.655; anddiamond, 2.417. The variation of refractive index with wavelength is the source ofchromatic aberrationinle...
A circle can be described by an equation that results from the application of theformula for adrawn in the circle. This triangle will have the hypothenuse equal to the radius of the circle, and the other sides given by segments over the x and y-axis. Substituting these elements in the ...

, ‘q’, which is the ratio of the length of the arc ‘s’ that an object traces on this circle to its radius ‘r’. It is the angular portion under the arc’s shadow, between the two lines originating from the center and connected to its ends. It is measured in radians....
therefore the substitution fails. Remember that we had Δv┴= vsinθ from above. You can see why Feynman suppressed that step. He didn't want it to suffer any scrutiny.Besides, the equation Δθ = s/r only works if θ is measured in radians.But Feynman cannot measure the angle in ra...
where FA is the flow accumulation, cell size is the size of DEM data (30 × 30 m), slope angle in radians, and m = 0.5 (0.4–0.7) and n = 1.3 (1.0–1.4) are the exponent values assigned as recommended by Mitasova et al. (1996) and Liu et al. (2000) because ...
