Trigonometry Formulas
All trigonometric formulas are divided into two major systems: The Trigonometric Identities and Trigonometric Ratios. Trigonometric Identities are some formulas that involve the trigonometric functions. These trigonometry identities are true for all values of the variables. Trigonometric Ratio is known for the relationship between measurement of the angles and the length of the side of the right triangle. Trigonometry Functions: In a right angled triangle, we have basically 3 sides namely – Hypotenuse, Opposite side and Adjacent side. The longest side is known as the hypotenuse, the side opposite to hypotenuse is opposite and the side where both hypotenuse and opposite rests is the adjacent side. There are basically 6 Laws used for finding the elements in Trigonometry. They are called trigonometric functions. The six trigonometric functions are sine, cosine, secant, co-secant, tangent and co-tangent. By using the above right angled triangle as reference, the trigo
