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

What is the relationship between the tan and cot?
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
What are the trigonometric functions?
sine, cosine, tangent, cosecant, secant and cotangent.
What are circular functions?
Sine, Cosine, Tangent, Cotangent, secant and cosecant
What are the six trigonometric functions of special angles?
sine, cosine, tangent, cosecant, secant and cotangent.
Trigonometry Identity Help Express cosecant in terms of cosine?
csc(x) = 1/sin(x) = +/- 1/sqrt(1-cos^2(x))
What is the relationship between the tan and cot?
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
Express sine in terms of cotangent?
sin(x) = [1 + cot^2(x)]^-0.5
What are the trigonometric functions?

What are circular functions?
Sine, Cosine, Tangent, Cotangent, secant and cosecant
In what quadrant is cosine negative and cotangent negative?
The second quadrant (top left).
What are the six trigonometry function?
sine, cosine, tangent, cosecant, secant, cotangent.
1 minus 2 cosine squared divided by sine cosine is equal to tangent minus cotangent?
No, it is not. To be correct, the expression requires parenthesis, which are missing.
What is Secany squared times cotangent times cosine?
Assuming that "secany" is meant to be secant, the answer is cosecant.
What are functions in trigonometry?
The basic functions of trigonometry are: sine cosine tangent secant cosecant cotangent
What are the six trigonometric functions of special angles?
sine, cosine, tangent, cosecant, secant and cotangent.
What is cot in trigonomentry?
Cot in trigonometry is the cotangent, which is cosine over sine, or x over y.
