Like sin 2 θ cos 2 θ = 1 and 1 tan 2 θ = sec 2 θ etc Such identities are identities in the sense that they hold for all value of the angles which satisfy the given condition among them and they are called conditional identities Trigonometric Identities With Examples定義 角 この記事内で、角は原則として α, β, γ, θ といったギリシャ文字か、 x を使用する。 角度の単位としては原則としてラジアン (rad, 通常単位は省略) を用いるが、度 (°) を用いる場合もある。 1周 = 360度 = 2 π ラジアン 主な角度の度とラジアンの値は以下のようになる： So, for every point on circle, we have a 2 b 2 = 1 or cos 2 x sin 2 x = 1 Since a complete revolution creates an angle of 2π radian = 360°, we have ∠AOB = π/2, ∠AOC = π and ∠AOD = 3π/2 Angles that are multiples of π/2 are called quadrantal angles The coordinates of the points A, B, C and D are already provided in the figure

Proportionality constants are written within the image sin θ, cos θ, tan θ, where θ is the common measure of five acute angles In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of a rightangled triangle to ratios of two side lengthsThe (π/2θ) formulas are similar to the (π/2θ) formulas except only sine is positive because (π/2θ) ends in the 2nd Quadrant sin (π / 2 θ) = cosθ cos (π / 2 θ) = sinθAs previously mentioned, the functions sin x and cos x are periodic with period 2 π sin(x 2 kπ) = sin x and cos(x 2 kπ) = cos x for any k ∈ Z Graphically, this means that once we have drawn a full period of each of the graphs of sin x and cos x, say in the interval 0, 2 π, we can obtain the full graphs of these two functions by
