In calculus, the derivative of sec(x) is sec(x)tan(x). This means that at any value of x, the rate of change or slope of sec(x) is sec(x)tan(x). |
Sec, Cosec and Cot A-Level maths revision. Secant, cosecant and cotangent are usually written as sec, cosec and cot, they are trigonometric functions. |
Csc Sec Cot is the abbreviated form of writing the trigonometric functions cosecant, secant, and cotangent functions. |
Calculate the secant of a value, defined as sec(x) = 1/cos(x) . To avoid confusion with the matrix secant, this function does not apply to matrices. |
The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . The secant of x is 1 divided by the cosine of x: sec x = 1. |
