Class 11 MATHS TRIGONOMETRIC RATIOS AND IDENTITIES cot(-pi/6) = -sqrt(3) We will use the following: (1) cot(x) = cos(x)/sin(x) (2) sin(-x) = -sin(x) (3) cos(-x) = cos(x) (4) cos(pi/6) = sqrt(3)/2 (5) sin(pi/6) = 1/2 Verification of these facts is a good exercise, and may be done using basic definitions together with the unit circle for 1-3.The Trigonometric Identities are equations that are true for Right Angled Triangles. Periodicity of trig functions. Sine, cosine, secant, and cosecant have period 2π while tangent and cotangent have period π. Identities for negative angles. Sine, tangent, cotangent, and cosecant are odd functions while cosine and secant are even functions.cot π 20 . cot 3 π 20 . cot 5 π 20 . cot 7 π 20 . cot 9 π 20 = · cot π 20 . cot 3 π 20 . cot 5 π 20 . cot 7 π 20 . · lf A,B,C and D are the angles of a cyclic ...The value of cot pi/4 can be calculated by constructing an angle of π/4 radians with the x-axis, and then finding the coordinates of the corresponding point (0.7071, 0.7071) on the unit circle. The value of cot pi/4 is equal to the x-coordinate (0.7071) divided by the y-coordinate (0.7071). ∴ cot pi/4 = 1.The other four trigonometric functions (tan, cot, sec, csc) can be defined as quotients and reciprocals of sin and cos, except where zero occurs in the denominator. It can be proved, for real arguments, that these definitions coincide with elementary geometric definitions if the argument is regarded as an angle given in radians . [6] Figure 6 The function f(x) = x3 is an odd function. We can test whether a trigonometric function is even or odd by drawing a unit circle with a positive and a negative angle, as in Figure 7. The sine of the positive angle is y. The sine of the negative angle is −y. The sine function, then, is an odd function.cot pi/4 = 1. cot pi/4 radians = 1. The cot of pi/4 radians is 1, the same as cot of pi/4 radians in degrees. To change pi/4 radians to degrees multiply pi/4 by 180° / π = 45°. Cot pi/4 = cot 45 degrees. Our results of cotpi/4 have been rounded to five decimal places. If you want cotangent pi/4 with higher accuracy, then use the calculator ...

So if we divide 1 by tanπ 2 we will have 1∞ which leads to 0. We can't 'divide' a number by tan(π/2); tan(x) is undefined at x = π/2, unless we edit the definition of tangent function.Regular Polygon Area = n × a² × cot(π/n) / 4; where n is the number of sides, and a is the side length.

In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just 'cot'. Of the six possible trigonometric functions, cotangent, secant, and cosecant, are rarely used. In fact, most calculators have no button for them, and software ...To find the value of cot π/8 using the unit circle: Rotate ‘r’ anticlockwise to form pi/8 angle with the positive x-axis. The cot of pi/8 equals the x-coordinate (0.9239) divided by y-coordinate (0.3827) of the point of intersection (0.9239, 0.3827) of unit circle and r.
