COT INVERSE(1/SQRT.3) IF SO......YOU HAVE TO REFER STAMNDARD TABLES OR USE CALCULATORS OR DRAW FROM YOUR MEMORY OF STANDARD ANGLES AND THEIR TRIGNOMETRIC RATIOS . STD.ANGLES ARE 0,30,45,60,90...ETC... TAN 60 = SQRT.(3)..WHICH IS TO BE COMMITTED TO MEMORY... SO COT (60)=1/SQRT(3) SO ANSWER IS 60 DEGREES ...OR...60*PI/180=PI/3 RADIANS.
