A formula for computing the trigonometric identities for the one-third angle exists, but it requires finding the zeroes of the cubic equation 4x 3 − 3x + d = 0, where is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.
Csc-1, CSC-1, csc-1, or csc −1 may refer to: csc x −1 = csc( x )−1 = excsc( x ) or excosecant of x , an old trigonometric function csc −1 y = csc −1 ( y ), sometimes interpreted as arccsc( y ) or arccosecant of y , the compositional inverse of the trigonometric function cosecant (see below for ambiguity)

The 2A46 (also called D-81TM) is a 125 mm/L48 smoothbore cannon of Soviet origin used in several main battle tanks. It was designed by OKB-9 (Artillery Plant No. 9) in Yekaterinburg . Description

A sabot (UK: / s æ ˈ b oʊ, ˈ s æ b oʊ /, US: / ˈ s eɪ b oʊ /) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel when fired.
[1] The gun could be depressed to -10° and raised to 30°. It had an arc of fire of 360°, meaning that they could rotate a full circle, able to fire at any given point. The gun fired a 28-kilogram (62 lb) high-explosive shell at a muzzle velocity of 830 meters per second (2,700 ft/s) to a range of 17,400 meters (19,000 yd). [2]
