Evaluate sin((7pi)/4) Mathway

WebFind the exact values of the sine, cosine, and tangent of the angle. 7π 12 = π 3 + π 4 sin(7pi/12)= cos(7pi/12)= tan(7pi/12)= This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. WebJun 1, 2016 · Explanation: This can also be shown through the sine half-angle formula: sin( x 2) = ± √ 1 − cos(x) 2. Here, since we want to find sin( 7π 8), we know that x 2 = 7π 8 and x = 7π 4. sin( 7π 8) = ⎷ 1 −cos(7π 4) 2. Note that the ± sign has just turned into a positive sign: the sine of 7π 8 will be positive since 7π 8 is in the ... WebSolution: Given, Sine of seven pi divided by eight i.e. sin(7π 8) s i n ( 7 π 8) We have to find the exact value by using a half-angle identity of sin(7π 8) s i n ( 7 π 8) Now, find sin(π 8) s i n ( π 8) by using trigonometric identity, The negative answer is rejected because sin(π 8) s i n ( π 8) is positive. buffet saint john nb
