How do you find sin and cos on the unit circle?
Space and AstronomyUsing the unit circle, the sine of an angle t equals the y-value of the endpoint on the unit circle of an arc of length t whereas the cosine of an angle t equals the x-value of the endpoint. How do you find Cos on a unit circle? The process for determining the sine/cosine of

What did Juan Vucetich do?
Space and AstronomyJuan Vucetich, an employee of the police of the province of Buenos Aires in 1888, devised an original system of fingerprint classification published in book form under the title Dactiloscopía comparada (1904; “Comparative Fingerprinting”). His system is still used in most Spanish-speaking countries. Who was Juan Vucetich and what did he do? Juan Vucetich (1858–1925),

What is the meaning of corresponding sides are proportional?
Space and AstronomyTwo triangles are said to be similar, if their corresponding angles are equal and corresponding sides are proportional i.e., the ratios between the lengths of the corresponding sides are equal. How do you know if a side is proportional? Video quote: You can find it by looking at the ratio of any pair of corresponding

How much heat does the earth radiate?
Space and AstronomyThe atmosphere radiates heat equivalent to 59 percent of incoming sunlight; the surface radiates only 12 percent. How much energy does the Earth emit? Together, the energy reaching Earth’s surface from the Sun and from the atmosphere is about 504 watts per square meter. Earth’s surface emits about 79% of that back out. The remaining

How did Red Giants get so big?
Space and AstronomyWhen the hydrogen in the centre of a star runs out, the star begins to use hydrogen further out from its core. This causes the outer layers of the star to expand and cool. Over time, the star grows to more than 400 times its original size. As the star cools, it changes colour and

What is CT pitch?
Space and AstronomyIn the spiral CT technique, the term pitch is known, which is the distance (speed) of the table for one x-ray rotation in gantry (l) compared to the number and width of the detector (nT). Pitch changes will affect the spatial resolution of the patient’s image and dose received. What does pitch mean in CT

How do you measure the diameter of a jar?
Space and AstronomyMeasure the Diameter Measure the bottom face of the bottle from one side to the other with a flat ruler. This is your bottle diameter. Multiply the diameter by pi (3.14), and the resulting number is your circumference. What is the diameter of a jar? Most Mason jars with regular mouths have an outer diameter

What is the difference between route pattern and translation pattern?
Space and AstronomyThe primary difference between route patterns and translation patterns is that translation patterns do not have a final path selection destination (route list, gateway, or trunk). Translation patterns exist only to manipulate digits; they do not perform call routing. What is Route pattern? A route pattern comprises a string of digits (an address) and a

How do you find the angle between two tangents?
Space and Astronomytan(α−θ)=tanα−tanθ1+tanαtanθ=−2√2−√21−2√2√2=√2. Hence the angle between the tangents at P is arctan√2≈0.955c≈54.7∘. It turns out that θ=α−θ and the triangle in the above diagram is isosceles. What is the formula to find angle between two tangents? 2 Answers. Show activity on this post. If m1 and m2 are the gradients of the two lines, the angle
