Secx or secant of x can be written in various forms such as, sec, cosec, and or cot can be defined as a trigonometric function like, sin, cos and tan. Forms of secx include the following:
sec x = 1cos x
cosec x 1sin x
cot x = 1tan x = cos x sin x
Secant can as well be obtained from complex number: secx = 2/[e^(ix) + e^(-ix)], where i is the imaginary unit that equals to sqrt (-1). In contrast to cos(x), finding the antiderivative of secant of x needs few calculus tricks. Moreover, the antiderivative of secx has many identical forms that can puzzle students who want to see how good they are at computing.

Social problem is defined as the issue or problem which includes seen by people of community as undesirable or undesired. But sociable problems are not under the control of an individual. Sociable problems mainly arise when there is a interpersonal disruption or sociable change.
