Question

$\lim_{x\to \ 0} 1/x(secx)(cosecx)$

Answer 1

Answer:

The tangent of x is defined to be its sine divided by its cosine: ... 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 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
