WebStep-by-Step Solution. Given that pi rad is equal to 180°, we can write the following radians to degrees conversion formula: Plugging the given angle value, in radians, in the previous formula, we get: α° = ( 2π/3 × 180/π) = 120 degrees. Using our 'radians to degrees converter' above, you can find the exact value of 2π/3 radians in ... WebSolve your math problems using our free math solver with step-by-step solutions.

WebCalculus. 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 … 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. grafclean paint
