 Examples – Trigonometric equations Based on what we have explained to the article Trigonometric equations, we are going to solve some exercises below: Example 1: Solve the equations. a) $displaystyle sin x=sin {{10}^{{}^circ }}$ Since the angles $displaystyle x$ and $displaystyle {{10}^{{}^circ }}$ have the same sinuses, they are connected with the equations: $displaystyle […] ### Trigonometric Equations By Math Original No comments Trigonometric equations What is a trigonometric equation? A trigonometric equation is any equation that contains a trigonometric function otherwise from trigonometric identities that are true for any angle a trigonometric equation may be true only for some certain angles in some cases. Solving Trigonometric Equations How to solve the equation$ displaystyle sin x=a$? Step […] ### Trigonometric Identities – Examples By Math Original No comments Trigonometric Identities – Examples Based on what we have explained to the article Trigonometric Identities, we are going to solve some exercises below: Example 1: Simplify a)$ displaystyle tan theta cot theta  displaystyle tan theta cot theta =$$displaystyle frac{{sin theta }}{{cos theta }}cdot frac{{cos theta }}{{sin theta }}=$$ displaystyle frac{{cancel{{sin theta }}}}{{cancel{{cos theta }}}}cdot frac{{cancel{{cos […] ### Trigonometric Identities

Trigonometric Identities Sine, tangent, cotangent and cosecant in mathematics an identity is an equation that is always true. Meanwhile trigonometric identities are equations that involve trigonometric functions that are always true. This identities mostly refer to one angle labelled $displaystyle theta$. Defining Tangent, Cotangent, Secant and Cosecant from Sine and Cosine \$ displaystyle tan […] ### Trigonometry
