Csc pi/2 - Find Value of Csc pi/2 Csc π/2 - Cuemath
WebMar 24, 2024 · By the definition of the functions of trigonometry, the sine of pi/2 is equal to the y-coordinate of the point with polar coordinates (r,theta)=(1,pi/2), giving sin(pi/2)=1. Similarly, cos(pi/2)=0, since it is the … WebJan 14, 2016 · f ( π 2) = csc( π 2) = 1 insert the values in the tangent line equation: ∴ y −1 = 0(x − π 2) y − 1 = 0 y = 1 Alternatively, without the derivation, if you remember from trigonometric that: y = csc(x) has a local minimum point in x0 = π 2 then you can affirm that the tangent line is y = f (x0) Answer link room a01 android 10 b4

WebFind csc( 45π) Ans: − 2 Explanation: csc( 45π) = sin( 45π)1 ... How do you find the exact value of csc( 65π) using the half angle formula? csc56π = 2. Explanation: Half-angle formula for sin is : sin(2θ) = ± 21−cosθ, ... Just follow the suggestion of Zack Ni: 3+12 2 = 3+12 2 ⋅ 3−13−1 = 3−12 6−2 2 = 6− 2. ... 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) of the point of intersection (0.7071, 0.7071) of unit circle and r. Hence the value of csc pi/4 = 1/y = 1.4142 (approx) WebSolve your math problems using our free math solver with step-by-step solutions.
