Evaluate csc (2pi) csc(2π) csc ( 2 π) Rewrite csc(2π) csc ( 2 π) in terms of sines and cosines. 1 sin(2π) 1 sin ( 2 π) Subtract full rotations of 2π 2 π until the angle is … WebIn algebra, a quadratic equation (from Latin quadratus 'square') is any equation that can be rearranged in standard form as where x represents an unknown value, and a, b, and c … can ibuprofen be used for swelling

Sin 2pi/3 - BRAINGITH

WebThe value of csc pi/3 can be calculated by constructing an angle of π/3 radians with the x-axis, and then finding the coordinates of the corresponding point (0.5, 0.866) on the unit … WebJan 8, 2024 · the csc of an angle cannot go to 0, so let's just use cot(3x/2) = 0, This happens at 3x/2 = pi/2, x = pi/3, and also at 3x/2 = 3pi/2, x = pi, AND: 3x/2 = 5pi/2, x = 5pi/3. f(x) goes to infinity when 3x/2 = pi, x = 2pi/3 and when 3x/2 = 2pi, x = 4pi/3. So, for 0 ≤ x ≤2pi, we have 4 discontinuities, 2 local minimums, and 1 local maximum. WebCosec 3pi/2 Using Unit Circle. To find the value of csc 3π/2 using the unit circle: Rotate ‘r’ anticlockwise to form 3pi/2 angle with the positive x-axis. The cosec of 3pi/2 equals the reciprocal of the y-coordinate (-1) of the point of intersection (0, -1) of unit circle and r. Hence the value of csc 3pi/2 = 1/y = -1. can ibuprofen cause a positive drug test
