Here is the derivation of the formula of integral of cot x by using integration by substitution method. For this, let us recall that cot x = cos x/sin x. Then ∫ cot x dx becomes. ∫ cot x dx = ∫ (cos x)/ (sin x) dx. Substitute sin x = u.Trigonometric co-function identities are relationships between the basic trigonometric functions (sine and cosine) based on complementary angles. They also show that the graphs of sine and cosine are identical, but shifted by a constant of \frac {\pi} {2} 2π. The identities are extremely useful when dealing with sums of trigonometric functions ...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. Hence the value of cot pi/8 = x/y = 2.4142 (approx) You could define cot x as 1/ tan x and fill in all the gaps by taking the limit, but that is overkill. tanπ2 is actually infinity. 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.There are several equivalent ways for defining trigonometric functions, and the proof of the trigonometric identities between them depend on the chosen definition. The oldest and somehow the most elementary definition is based on the geometry of right triangles.The proofs given in this article use this definition, and thus apply to non-negative angles not …A.y=sin(π/2-x) .
