Returns the cosecant of an angle.
פונקציה זו פועלת ב-Google Sheets בדיוק כמו ב-Excel — אותה תחביר ואותם ארגומנטים.
CSC(number)The CSC function calculates the cosecant of an angle specified in radians. It is the reciprocal of the sine function, defined as 1/SIN(number).
=CSC(PI()/2)תוצאה: 1
Calculates the cosecant of PI/2 radians (90 degrees), which is 1.
=CSC(RADIANS(30))תוצאה: 2
Calculates the cosecant of 30 degrees by converting it to radians first.
The function will return a #NUM! error because the cosecant is undefined when the sine is zero.
