arccosine's Usage Examples:

Alternatively, the derivative of arcsecant may be derived from the derivative of arccosine using the chain rule.

from the origin and lines of constant natural frequency can be drawn as arccosine whose center points coincide with the origin.

arcsine y arcsin(x) x sin(y) −1 ≤ x ≤ 1 −π/2 ≤ y ≤ π/2 −90° ≤ y ≤ 90° arccosine y arccos(x) x cos(y) −1 ≤ x ≤ 1 0 ≤ y ≤ π 0° ≤ y ≤ 180° arctangent.

number ACS number EXTENDED MODE then SYMBOL SHIFT+W Function Returns the arccosine of number AND SYMBOL SHIFT+Y Logical operator Returns true if both conditions.

arccos is the principal value of the arccosine function.

By Cauchy–Schwarz inequality, the argument of the arccosine is in the interval [−1, 1].

This phase-shifted triangle wave can also be expressed with cosine and arccosine: y ( x ) a − 2 a π arccos ⁡ ( cos ⁡ ( 2 π p x ) ) .

} If det(B) is complex or is greater than 2 in absolute value, the arccosine should be taken along the same branch for all three values of k.

The inverse function of the lemniscate cosine is the lemniscate arccosine.

this formula for φ may be stated a little more simply using the standard arccosine function: ϕ { arccos ⁡ ( x r ) if  y ≥ 0  and  r ≠ 0 − arccos ⁡ ( x.

from 0° to 180°, and does not pose any problem when calculated from an arccosine, but beware for an arctangent.

interval [0, π] onto the interval [–1, 1], and its inverse function, called arccosine, maps [–1, 1] onto [0, π].

trigonometric function cos−1y cos−1(y), sometimes interpreted as arccos(y) or arccosine of y, the compositional inverse of the trigonometric function cosine (see.
