: secante

To find the secant of an angle, you take the reciprocal of the cosine value of that angle.

That is the fastest easiest way to find cosecant, secant and cotangent.

Examples

And it looks to me like we get R equals tan Theta secant Theta by solving.
This is natural log absolute value secant X plus tangent X.
Plus one divided by the secant of gamma.
So it's F secant alpha squared.
And when we do that, we'll say secant X, tangent of X.
So you're just left with what secant squared of X.
So our integral we're just left with secant of Theta D Theta.
I'm going to rewrite this as secant of X minus cosine of X.
Do you remember tangents and secants from trigonometry?

Etymology

Secant takes its name from the same Latin secare, 'to cut', because it was first used for a line that cuts a circle. So in trigonometry secant is the value you get when you divide 1 by the cosine, linking the name to that cutting line.
