Sin (θ), Tan (θ), and 1 are the heights to the line starting from the x axis, while Cos (θ), 1, and Cot (θ) are lengths along the x axis starting from the origin The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functionsProportionality 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 complementary angle equals the given angle subtracted from a right angle, 90° For instance, if the angle is 30°, then its complement is 60° Generally, for any angle θ, cos θ = sin (90° – θ) Written in terms of radian measurement, this identity becomes cos θ = sin (π/2 – θ

The trigonometric R method is a method of rewriting a weighted sum of sines and cosines as a single instance of sine (or cosine) This allows for easier analysis in many cases, as a single instance of a basic trigonometric function is often easier to work with than multiple are The R method is most often used to find the extrema (maximum and minimum) of combinations of trigonometricTherefore, we will leave theSin1 sin 5 π 6 = sin1 sin π π 6 ∵ sin π θ = sin θ = sin1 sin π 6 ∵ Principal value ∈ 0, π 2 = π 6 which is the required principal value Answer
