WebUnit Circle. Illustration of a unit circle (circle with a radius of 1) superimposed on the coordinate plane. The circle is divided into four quadrants by the x- and y- axes. The circle can be labeled and used to find the six trigonometric values (sin, cos, tan, cot, sec, csc, cot) at each of the quadrantal angles. WebJun 26, 2024 · cosecant is 1/sine. secant is 1/cosine. cotangent is 1/tangent. So thinking about the above things in bold, cot45∘ = adjacent/opposite. csc45∘ = hypotenuse/opposite. sec45∘ = hypotenuse/adjacent. Now look at your drawing of the 45∘ right triangle and plug in the lengths specified in the above fractions for each trig function.
