sine vs cosine vs tangent Depending on which sides you have you should choose sin cos or tan as shown in the diagram below begin align sin d frac text opposite side text hypoteneuse side cos d frac text adjacent side text hypoteneuse side tan d frac text opposite side text adjacent side end align
This page explains the sine cosine tangent ratio gives on an overview of their range of values and provides practice problems on identifying the sides that are opposite and adjacent to a given angle The Sine Cosine and Tangent functions express the ratios of sides of a right triangle The Inverse Sine Cosine and Tangent graphs are Inverse Sine Inverse Cosine Inverse Tangent Mirror Images Here is Cosine and Inverse Cosine plotted on the same graph Cosine and Inverse Cosine They are mirror images about the diagonal The same is true for Sine and Inverse Sine and for Tangent and Inverse Tangent

We define the three trigonometrical ratios sine cosine and tangent as follows we normally write these in the shortened forms sin cos and tan sin theta text opposite text hypotenuse cos theta text adjacent text hypotenuse tan theta text opposite text adjacent Sin A B sin A cos B cos A sin B cos A B cos A cos B mnplus sin A sin B tan A B tan A tan B 1 mnplus tan A tan B cot A B cot A cot B mnplus 1cot B cot A
To find sin cos and tan we use the following formulas sin Opposite Hypotenuse cos Adjacent Hypotenuse tan Opposite Adjacent For finding sin cos and tan of standard angles you can use the trigonometry table What is the Table for Sine Cosine and Tangent in Trigonometry Sin is equal to the side opposite the angle that you are conducting the functions on over the hypotenuse which is the longest side in the triangle Cos is adjacent over hypotenuse And tan is opposite over adjacent which means tan is
