The measure of the angle is 180º. Some examples are shown below: Right angle: It is one-quarter of a whole turn and is the same as the angle made by a horizontal line and vertical line. The measure of the angle is 90º.

WebHalf angle formulas can be derived from the double angle formulas, particularly, the cosine of double angle. For easy reference, the cosines of double angle are listed below: cos 2θ = 1 - 2sin2 θ → Equation (1) cos 2θ = 2cos2 θ - 1 → Equation (2) Note that the equations above are identities, meaning, the equations are true for any value of the variable θ.

WebField of view is the area of the inspection captured on the camera’s imager. The size of the field of view and the size of the camera’s imager directly affect the image resolution (one determining factor in accuracy). Working distance is the distance between the back of the lens and the target object. WebIn this case, x 4 = 1 2 × x 2. Therefore, this is the formula for the cosine of half of the half angle. Now, let y = 2 x. Then, replace all of the x terms in the equation for the cosine of a half-angle with y 2. The new equation reads: c o s ( y 2 2) = c o s y 2 + 1 2. Then, use the original half angle formula and the fact that y 2 2 = x 4 to ...
