How do you use the ordered pairs on a unit circle to evaluate a trigonometric function of any angle? What is the reference angle for #140^\circ#? ... WebSep 15, 2024 · Figure 1.4.2 Angle greater than 360 . We can now define the trigonometric functions of any angle in terms of Cartesian coordinates. Recall that the xy-coordinate plane consists of points denoted by pairs (x, y) of real numbers. The first number, x, is the point's x coordinate, and the second number, y, is its y coordinate.
Sec 390 Degrees - Find Value of sec 390 Degrees Sec …
WebThe angle 390°, coterminal to angle 30°, is located in the First Quadrant (Quadrant I). Since sine function is positive in the 1st quadrant, thus sin 390 degrees value = 1/2 or 0.5. Similarly, sin 390° can also be written as, sin 390 degrees = (390° + n × 360°), n ∈ Z. ⇒ sin 390° = sin 750° = sin 1110°, and so on. WebThe angle 390°, coterminal to angle 30°, is located in the First Quadrant (Quadrant I). Since secant function is positive in the 1st quadrant, thus sec 390 degrees value = 2/√3 or 1.1547005. . . ⇒ sec 390° = sec 750° = sec 1110°, and so on. Note: Since, secant is an even function, the value of sec (-390°) = sec (390°). rice university average act
