Sorry, no etymologies found.
Add together the secant of the Latitude, the cosecant of the P.D., the cosine of the Half Sum and the sine of the Difference (Table 44).
After the creation of the universe, light speed declined following a curve approximating the curve of the cosecant squared.
On this topic, it isn't completely clear to me why we make kids memorize what the secant, cosecant, and cotangent are.
If your calculator does not have keys for the cosecant (csc), secant (sec), or cotangent (cot) functions, ﬁ rst
Graph of the secant function for values of x between -3 rad and 3 rad. is the same as the range of the cosecant function.
They are known as the hyperbolic sine, hyperbolic cosine, hyperbolic tangent, hyperbolic cosecant, hyperbolic secant, and hyperbolic cotangent.
If we are operating on some variable x, the arctangent of x is denoted tanÀ1 (x) or arctan (x) The inverse of the cosecant function is the arccosecant function.
This should not come as a surprise, because the cosecant and secant functions are the reciprocals of the sine and cosine functions, respectively, and the sine and cosine are horizontally displaced by 1 = 4 cycle.
SOLUTION 4-1 Remember that the hyperbolic cosecant (csch) is the reciprocal of the hyper - bolic sine (sinh).
The cosecant and secant functions have the same general shape, but they are shifted by 90 (/2 rad), or 1 = 4 cycle, with respect to each other.
