Trigonometry
Tip: There are 2 * pi radians in a full circle of 360 degrees. A formula to convert degrees to radians is: radians = degrees divided by 57.29577951 Here are some helpful functions to convert degrees to radians, radians to degrees and to calculate PI.
function pi()
pi = asn(1) * 2
end function
function rad2deg(num)
rad2deg = 90 / asn(1) * num
end function
function deg2rad(num)
deg2rad = asn(1) / 90 * num
end function
Description:
This function returns the arc cosine of the number or numeric expression n. The return value is expressed in radians.
Usage:
print "The arc cosine of 0.2 is "; acs(0.2)
Description:
This function returns the arc sine of the number or numeric expression n. The return value is expressed in radians.
Usage:
print "The arc sine of 0.2 is "; asn(0.2)
Description:
This function returns the arc tangent of the number or numeric expression n. The return value is expressed in radians.
Usage:
print "The arc tangent of 0.2 is "; atn(0.2)
Description:
This function returns the cosine of the angle n. The angle n should be expressed in radians.
Usage:
for c = 1 to 45
print "The cosine of "; c; " is "; cos(c)
next c
Description:
This function returns the sine of the angle n. The angle n should be expressed in radians.
Usage:
for t = 1 to 45
print "The sine of "; t; " is "; sin(t)
next t
This function returns the tangent of the angle n. The angle n should be expressed in radians
Usage:
for t = 1 to 45
print "The tangent of "; t; " is "; tan(t)
next t
