If you know the measure of one angle, and the length of one side of a triangle, you can find the measures of the other sides and angles. From there, you can find the values of the other trig functions.
cos (x) = sin (90-x) in degrees
there are other identities such as cos^2+sin^2=1, so cos^2=1-sin^2

What are the trigonometric functions?
sine, cosine, tangent, cosecant, secant and cotangent.
What are circular functions?
Sine, Cosine, Tangent, Cotangent, secant and cosecant
Why are sine and cosine functions called harmonic?
Sinusoid shape of the sine and cosine functions appear as oscillations. If an object is moving in a straight line and its position (function of time) can be described as sinusoid then it is referred to as a simple harmonic motion.
What is trigonometry's circular function?
The basic circular functions are sine, cosine and tangent. Then there are their reciprocals and inverses.
What are the six trigonometric functions of special angles?
sine, cosine, tangent, cosecant, secant and cotangent.
