How to Find Trigonometric Functions?
The sine function is defined as the ratio of the length of the opposite side to that of the length of the hypotenuse in a rightangled triangle. Sine is a trigonometric function of an angle. It is denoted as sinθ, where θ is the angle between the two sides.
The cosine function is defined as the ratio of the length of the adjacent side to that of the length of the hypotenuse in a rightangled triangle. Cosine is a trigonometric function of an angle. It is denoted as cosθ, where θ is the angle between the two sides.
The tangent function is defined as the ratio of the length of the opposite side to that of the length of the adjacent side in a rightangled triangle. Tangent is a trigonometric function of an angle. It is denoted as tanθ, where θ is the angle between the two sides.
The cosecant function is defined as the ratio of the length of the hypotenuse to that of the length of the opposite side in a rightangled triangle. Cosecant is a trigonometric function of an angle. It is denoted as cosecθ, where θ is the angle between the two sides. It is the inverse of sinθ.
The secant function is defined as the ratio of the length of the hypotenuse to that of the length of the adjacent side in a rightangled triangle. Secant is a trigonometric function of an angle. It is denoted as secθ, where θ is the angle between the two sides. It is the inverse of cosθ
The cotangent function is defined as the ratio of the length of the adjacent side to that of the length of the opposite side in a rightangled triangle. Cotangent is a trigonometric function of an angle. It is denoted as cotθ, where θ is the angle between the two sides. It is the inverse of tanθ.
