Question

Identify the equation which has a solution equal to ﻿2π3\frac{2\pi}{3}32π​﻿ .

Accepted Answer

﻿x=cos⁡−1(−12)x=\$$cos^{-1}$$\left(-\frac12\right)x=cos−1(−21​)﻿

Answer

﻿x=cos⁡−1(−22)x=\$$cos^{-1}$$\left(-\frac{\sqrt2}{2}\right)x=cos−1(−22​​)﻿

Answer

﻿x=tan⁡−1(−1)x=\$$tan^{-1}$$\left(-1\right)x=tan−1(−1)﻿

Answer

﻿x=sin⁡−1(22)x=\$$sin^{-1}$$\left(\frac{\sqrt2}{2}\right)x=sin−1(22​​)﻿
