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 ...

WebMay 28, 2024 · Figure 2.2. 1: Graph of the secant function, f ( x) = sec x = 1 cos x. Because there are no maximum or minimum values of a tangent function, the term amplitude cannot be interpreted as it is for the sine and cosine functions. Instead, we will use the phrase stretching/compressing factor when referring to the constant A. WebApr 28, 2015 · Zor Shekhtman. Apr 28, 2015. First of all, recall the definition of sec: sec(α) = 1 cos(α) To determine cos( 3π 2), recall the definition of cos based on a concept of a unit circle: cos(α) is an abscissa (X-coordinate) of a point on a unit circle, which radius makes an angle α with a positive direction of the X-axis, counting from that ...
