WebMay 24, 2015 · Well, csc(x) = 1 sin(x) so basically, I would find sin( π 2) and use it to get: csc( π 2) = 1 sin(π 2) = 1 1 = 1. Graphically: Remember also that: Answer link. WebTo find the value of csc π/4 using the unit circle: Rotate ‘r’ anticlockwise to form pi/4 angle with the positive x-axis. The csc of pi/4 equals the reciprocal of the y-coordinate (0.7071) …
WebTherefore, SIN/COS = TAN/1 . You can also see that 1/COS = SEC/1 and 1^2 + TAN^2 = SEC^2. A bunch of those almost impossible to remember identities become easier to remember when the TAN and SEC become legs of a triangle and not just some ratio of other functions. The angle line, COT line, and CSC line also forms a similar triangle. WebMar 24, 2024 · To derive these formulas, use the half-angle formulas. (13) (14)
WebExplanation: For cos 2pi/3, the angle 2pi/3 lies between pi/2 and pi (Second Quadrant ). Since cosine function is negative in the second quadrant, thus cos 2pi/3 value = - (1/2) or -0.5. Since the cosine function is a periodic function, we can represent cos 2pi/3 as, cos 2pi/3 = cos (2pi/3 + n × 2pi), n ∈ Z. ⇒ cos 2pi/3 = cos 8pi/3 = cos ... WebThe angles that they're picking are ones that can be made by adding angles that are easy to remember, namely pi/6, pi/4, pi/3, and pi/2 (30, 45, 60, and 90, respectively) and their multiples. You can use angle addition to quickly find the trig values of, say, 75 degrees, since it's easy to see that 45+30=75.
WebApr 19, 2024 · Explanation: π 3 is 60∘ so this is trig's biggest cliche, the 30,60,90 right triangle, half an equilateral triangle. The hypotenuse is 1, the short side adjacent to the 30∘ angle is 1 2 and by the Pythagorean Thoerem the long side is √12 −( 1 2)2 = √3 2. cos( π 3) = cos(60∘) = adjacent hypotenuse = 1 2.
WebFeb 1, 2024 · However, the above formulas, with all their grace, have a major flaw.
