cos(x)=sin(x-tau/4)
tan(x)=sin(x)/cos(x)
sin(x)=tan(x)*cos(x)
cos(x)=tan(x-tau/4)*cos(x-tau/4)
you can see that we have some circular reasoning going on, so the best we can do is express it as a combination of sines and cotangents:
cos(x)=1/cot(x-tau/4)*sin(x-tau/2)
tau=2*pi
1/(tangent of angle)
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.

sine, cosine, tangent, cosecant, secant and cotangent.
csc(x) = 1/sin(x) = +/- 1/sqrt(1-cos^2(x))
1/(tangent of angle)
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
sin(x) = [1 + cot^2(x)]^-0.5
The principal Trigonometric function is Sine(Sin). It has a complementary function Cosine (Cos). Bases on these two functions, are further trig. functions. they are. Tangent(Tan) = Sin /Cos Cosecant(CSC) = 1/Sin Secant (SEC) = 1/Cos Cotangent(COT) = Cos/Sin The word 'Sine' comes from Latin , and means 'curve'. Initially you learn it between 0 - 90 degrees. It is a continuous 'wave', from infinity to infinity. . The Sin/Cos functions only range from -1 to 1 through '0'. The Tan function ranges from negative infinity to positive infinity, through '0'. For a triangle inscribed in a circle. At the circles centre, the radius may be '1' unit. If the radius is angles at 30 degrees from the horizontal(x) axis, then the vertical (opposite) lines perpendicular height of the triangle is exactly '1/2' ( 0.5), compared to the radius. Hence the Sin( 30 degrees) is opposite / radius(hypotenuse) = (1/2)/1 = 1/2 All the othesr trig. functional answer are based on moving the radius from horizontal to vertical. with in the described circle. This is why it produces , such 'horrible' decimal figures. Have a look in Castle's Four Figures Tables, rather than using a pocket calculator, and also graphs of the Sine/Cosine and Tangent curves.

Reciprocal of tangent is '1 /tangent' or ' Cosine / Sine '
No, it is not. To be correct, the expression requires parenthesis, which are missing.
Cot in trigonometry is the cotangent, which is cosine over sine, or x over y.

Assuming that "secany" is meant to be secant, the answer is cosecant.
