WebThe secant function is the reciprocal of the cosine function. In Figure 6.4.1, the secant of angle t is equal to 1 cost = 1 x, x ≠ 0. The secant function is abbreviated as sec. The … WebThe CAST diagram tells us the quadrants for which various trigonometric functions are positive. To use this diagram, we first need to write c s c ( − 2 2 5) ∘, in terms of sine and cosine. We recall the following reciprocal trigonometric identity: c s c s i n 𝜃 ≡ 1 𝜃; therefore, c s c s i n ( − 2 2 5) = 1 ( − 2 2 5). ∘ ∘.

Web7 years ago. You have to know that sin (30 degrees) = sin (pi/6) is 1/2. This is the only trig function you have to memorize. Then, from the Pythagorean theorem, cos (30) is rt (3)/2. You can figure out sin (45) (see this video). From these you can get all the 12 simplest angles on the unit circle (8 multiples of 30 deg, 4 multiples of 45 (plus ...
