Functions in Calculate

These are the list of functions available in Calculate Activity:

• abs(x) - return absolute value of x, which means -x for x < 0
• acos(x) - return the arc cosine of x. This is the angle for which the cosine is x. Defined for -1 <= x < 1
• acosh(x) - return the arc hyperbolic cosine of x. This is the value y for which the hyperbolic cosine equals x.
• and(x, y) - logical and returns True if x and y are True, else returns False
• add(x, y) - return x + y
• asin(x) - return the arc sine of x. This is the angle for which the sine is x. Defined for -1 <= x <= 1
• asinh(x) - return the arc hyperbolic sine of x. This is the value y for which the hyperbolic sine equals x.
• atan(x) - return the arc tangent of x. This is the angle for which the tangent is x. Defined for all x
• atanh(x) - return the arc hyperbolic tangent of x. This is the value y for which the hyperbolic tangent equals x.
• b10bin(x) - interpret a number written in base 10 as binary, e.g.: b10bin(10111) = 23.
• ceil(x) - return the smallest integer larger than x.
• cos(x) - return the cosine of x. This is the x-coordinate on the unit circle at the angle x
• cosh(x) - return the hyperbolic cosine of x. Given by (exp(x) + exp(-x)) / 2
• div(x, y) - returns x/y where y!=0.
• gcd(a, b) - determine the greatest common denominator of a and b.For example, the biggest factor that is shared by the numbers 15 and 18 is 3.
• exp(x) - return the natural exponent of x. Given by e^x
• factorial(n) - return the factorial of n. Given by n * (n - 1) * (n - 2) * ... * 1
• factorize(x) - determine the prime factors that together form x. For examples: 15 = 3 * 5.
• floor(x) - return the largest integer smaller than x.
• inv(x) - return the inverse of x, which is 1 / x
• is_int(n) - determine whether n is an integer.
• is_prime(x) - Check if a number is a prime.For examples: is_prime(2).
• ln(x) - return the natural logarithm of x. This is the value for which the exponent exp() equals x. Defined for x >= 0.
• log10(x) - return the base 10 logarithm of x. This is the value y for which 10^y equals x. Defined for x >= 0.
