<prompt> Fumana boleng bo nepahetseng ba polelo ena ea trigonometric.cosπ3  <response>: Instruction in English: Find the exact value of this trigonometric expression. . Response in English: The value of cosπ3 is 12.Explanation: In trigonometry, π radians is equivalent to 180 degrees.So if we convert π3 to degrees, it becomes 180 13 60 degrees. So cosπ3 is the same as cos60.Using the unit circle, we know that the cosine of an angle is equal to the x-coordinate of the point on the unit circle that corresponds to that angle. The x, y coordinates of point on the unit circle corresponding to 60 degrees is 12, 32, so the value of cos60 or cosπ3 is 12. . Response in Sesotho: Boleng ba cosπ3 ke 12. Tlhaloso: Ho trigonometry, π radians e lekana le likhato tse 180. Kahoo haeba re fetola π3 ho likhato, e fetoha 180 13 60 likhato. Kahoo cosπ3 e tšoana le cos60. Ha re sebelisa selikalikoe sa yuniti, rea tseba hore cosine ea angle e lekana le x-coordinate ea ntlha ho selikalikoe sa yuniti e tsamaellanang le angle eo. The x, y likhokahano tsa ntlha selikalikoeng sa yuniti e tsamaellanang le likhato tse 60 ke 12, 32, kahoo boleng ba cos60 kapa cosπ3 ke 12.
