Inverse cosine in degrees
Y = acosd(X) returns
the inverse cosine of the elements of X in degrees.
Verify that inverse cosine of 0 is exactly
Show that inverse cosine, followed by cosine,
returns the original values of X.
acosd([2 3]) returns two complex angles,
which are then passed to the cosd function. cosd returns
the original values, 2 and 3.
X — Cosine of anglescalar value | vector | matrix | N-D array
Cosine of angle, specified as a real-valued or complex-valued
scalar, vector, matrix, or N-D array. The acosd operation
is element-wise when X is nonscalar.
Data Types: single | double
Complex Number Support: Yes
Y — Angle in degreesscalar value | vector | matrix | N-D array
Angle in degrees, returned as a real-valued or complex-valued
scalar, vector, matrix, or N-D array of the same size as X.
