Apr 4, 2023 · The cofunction graphs: sin and cos, tan and cot, sec and csc. The sine and cosine (sin and cos), tangent and cotangent (tan and cot), and secant and cosecant (sec and csc) are six trigonometric functions. So, each pair has a “basic” function and a function with the same name to which you add the prefix “co.” The Pythagorean Identities are based on the properties of a right triangle. cos 2 θ + sin 2 θ = 1. 1 + cot 2 θ = csc 2 θ. 1 + tan 2 θ = sec 2 θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan ( − θ ) = − tan θ. Look at the picture above. Every angle is measured from the positive part of the x-axis to its terminal line (the line that determines the end of the angle) traveling counterclockwise. If you want to find the reference angle, you have to find the smallest possible angle formed by the x-axis and the terminal line, going either clockwise or …Lời giải: ⇒ Kết hợp hai trường hợp suy ra số nghiệm của phương trình thuộc khoảng (0; 6π) là 9 nghiệm.
