How to find the value of tan81 degree and what is its value
1 Answer
ayushi jaimani
since the angle between 0 and 90 degrees, it is located in first quadrant nd in the first quadrant the values for sin,cos nd tan are positive. 81 is less than 90 and hence its an accute angle
tan81 = cot(90-81) = cot 9=6.313
