What is the value of sin (nπ /2)? - Quora. Something went wrong.Hence. sinx = 1 2 ⇒ x1 = π(2n + 1 6) or x2 = π(2n + 5 6) where n is an integer. But hence x belongs to [0,2π) the acceptable solutions are. x1 = π 6 and x2 = 5 ⋅ π 6. Answer link. Hence sinx=1/2=>x_1=pi (2 n+1/6) or x_2=pi (2 n+5/6) where n is an integer But hence x belongs to [0,2pi) the acceptable solutions are x_1=pi/6 and x_2=5*pi/6. Trigonometry. Find the Exact Value sin (2pi)^2. sin2 (2π) sin 2 ( 2 π) Subtract full rotations of 2π 2 π until the angle is greater than or equal to 0 0 and less than 2π 2 π. sin2(0) sin 2 ( 0) The exact value of sin(0) sin ( 0) is 0 0. 02 0 2. Raising 0 0 to any positive power yields 0 0. 0 0. sin pi/4 radians = √(2)/2. The sin of pi/4 radians is √(2)/2, the same as sin of pi/4 radians in degrees. To change pi/4 radians to degrees multiply pi/4 by 180° / $\pi$ = 45°. Sin pi/4 = sin 45 degrees. Our results of sinpi/4 have been rounded to five decimal places. If you want sine pi/4 with higher accuracy, then use the calculator ...How do you know if #sin 30 = sin 150#? How do you show that #(costheta)(sectheta) = 1# if #theta=pi/4#? See all questions in Trigonometric Functions of Any AngleUsually, the chosen domain is -π/2 ≤ y ≤ π/2. This means that the range of the inverse function will be equal to the range of a principal function; thus, the range of the arcsin function is [−π/2,π/2], and the …Feb 6, 2013 ...

How do you find the trigonometric functions of values that are greater than #360^@#? How do you use the reference angles to find #sin210cos330-tan 135#? Sin π /2 can also be expressed using the equivalent of the given angle (π /2) in degrees (90°). We know, using radian to degree conversion, θ in degrees = θ in radians × (180 °/ π) π /2 radians= π /2 × (180 °/ π) = 90° or 90 degrees Therefore sin π /2 = sin (90 °) = 1. Methods to Find Value of Sin pi/2 The Value of sin π /2 Noble Mushtak. [cos (θ)]^2+ [sin (θ)]^2=1 where θ has the same definition of 0 above. This is similar to the equation x^2+y^2=1, which is the graph of a circle with a radius of 1 centered around the origin. This is how the unit circle is graphed, which you seem to understand well..
