Notice the example of the ACOS function shown in Figure 10.2.
This is the cosine of the angle you want. It must be from –1 to 1.
To convert the result from radians to degrees multiply the number
The ACOS function
returns an angle of
which cosine is the
ACOSH returns the inverse hyperbolic cosine of a NUMBER . The number must be greater than or
equal to one.
An inverse hyperbolic cosine is the value in which the hyperbolic cosine is the number. For
example, ACOSH(COSH(number)) equals the number.
The real number greater than or equal to one.
ASI The ASIN function returns the arcsine of a number. The arcsine is the angle of which sine is
number. The returned angle is given in radians in the range –pi/2 to pi/2.
The number is the sine of the angle you want and it is bounded by the range of –1 to 1.
As with all normal trigonometric functions in Excel, you can convert the result from radians
to degrees by multiplying it by 180/PI().
Notice the example of the ASIN function shown in Figure 10.3. The destination of the plane
flying at 450 miles per hour is at 16 degrees south of west. If the wind velocity is 30 miles per
hour from the east, what course should the pilot set?
The sine of the desired angle. It must be from –1 to 1.
