WebSpecific uses Astronomy. In astronomy, the angular size or angle subtended by the image of a distant object is often only a few arcseconds, so it is well suited to the small angle approximation. The linear size (D) is related to the angular size (X) and the distance from the observer (d) by the simple formula: = where X is measured in arcseconds..

WebThese are the magnitudes of \vec {a} a and \vec {b} b, so the dot product takes into account how long vectors are. The final factor is \cos (\theta) cos(θ), where \theta θ is the angle between \vec {a} a and \vec {b} b. This tells us the dot product has to do with direction. Specifically, when \theta = 0 θ = 0, the two vectors point in ... WebPrecalculus. Solve for ? cos (theta)=-1/2. cos (θ) = − 1 2 cos ( θ) = - 1 2. Take the inverse cosine of both sides of the equation to extract θ θ from inside the cosine. θ = arccos(−1 2) θ = arccos ( - 1 2) Simplify the right side. Tap for more steps... θ = 2π 3 θ = 2 π 3.

WebYou would need an expression to work with. For example: Given sinα = 3 5 and cosα = − 4 5, you could find sin2α by using the double angle identity. sin2α = 2sinαcosα. sin2α = 2(3 5)( − 4 5) = − 24 25. You could find cos2α by using any of: cos2α = cos2α −sin2α. cos2α = 1 −2sin2α. cos2α = 2cos2α − 1.
