1. Funzioni trigonometriche

2. FunctionSyntaxDescription SIN=SIN(angle) Returns the sine of the given angle, where angle is in radians. COS=COS(angle) Returns the cosine of the given angle, where angle is in radians. TAN=TAN(angle) Returns the tangent of the given angle, where angle is in radians. ASIN=ASIN(n) Returns the inverse sine of the given number, n, where n must be within the range -1 to 1. The returned angle is in radians and within the range -  /2 to  /2. ACOS=ACOS(n) Returns the inverse cosine of the given number, n, where n must be within the range -1 to 1. The returned angle is in radians and within the range 0 to . ATAN=ATAN(n) Returns the inverse tangent of the given number, n. The returned angle is in radians and within the range -  /2 to  /2.

3. Funzioni The trigonometric functions take or return angles in radians. However, often degrees are more convenient to work with. Excel provides two functions making conversions between radians and degrees easy: RADIANS and DEGREES. Use RADIANS(angle) to convert an angle from degrees to radians. Use DEGREES(angle) to convert an angle from radians to degrees. For example, =COS(RADIANS(45)) returns the cosine of the angle 45 degrees.
