The exact value of cot(π4) cot ( π 4 ) is 1 The angle 5pi/3 is in the fourth quadrant (meaning cosine is positive while sine & tangent are negative), and its reference angle is 60 degrees with respect to the horizontal Therefore its sine is sqrt(3)/2, its cosine is 1/2, and its tangent is sqrt(3)This is the first choiceWell the value of Cot 90 is 0 Now split the cot in the form cos/sin cot = cos/sin cot 90 = cos 90/sin 90 (now put the values cos 90 = 0 and sin 90 = 1) cot 90 = 0/1 so the answer is Zero and if there is any problem feel free to correct me · The Cot function returns the cotangent of its argument, The returned angle is given in radians in the range π/2 to π/2 The Atan2 function returns the arctangent, or inverse tangent, of the specified x and y coordinates as arguments The arctangent is the angle from the xaxis to a line that contains the origin (0, 0) and a point with coordinates (x, y) The angle is given in
