Correct answers 3 question If the value of cos theta =√3/2then find the minimum positive value For cosine, you would use the same process Just remember the cosine of an angle is the side adjacent to the angle divided by the hypotenuse of the triangle In the diagram, the adjacent side is a and the hypotenuse is c, so costheta=a/c To find theta, you use the arccos function, which has the same relationship to cosine as arcsin has to sineGiven, cos theta = 21/29 We know that sin^2 theta=1cos^2 theta Hence (sin theta)^2 = 1(21/29)^2 → sin theta = /29 or /29 Depending on the quadrant in which theta lies we will select the sign, ie if theta lies in first or second quad then sin theta = /29 and if theta lies in third or fourth quad then sin theta = /29 Hope you got it
