In mathematics, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables where both sides of the equality are defined. The puzzle uses fundamental trig. Students cut out the shapes in the printout and put them together by matching questions and answers on corresponding sides to create the shape in the given solution. Equations, Solving Trigonometric Equations using There are numerous trigonometric identities which are determined by the essential trigonometric functions for instance sin, cos, tan, and so forth. at Standard Position and Coterminal Angles, Coterminal Does not the one you were looking for appear? Using the Reference Angle, Finding The puzzle can also be done individually or as a pair or group work activity. Now, Let's solve some basic problems based on these three trigonometric identities. \end{align} \], \[\left( {1 + \frac{1}{{{{\tan }^2}\theta }}} \right)\left( {1 + \frac{1}{{{{\cot }^2}\theta }}} \right) = \frac{1}{{{{\sin }^2}\theta - {{\sin }^4}\theta }}\], \[\begin{align}&LHS = (1 + {\cot ^2}\theta )\left( {1 + {{\tan }^2}\theta } \right)\\ &\qquad\;= {\text{cosec}^2}\theta \times {\sec ^2}\theta \\ &\qquad\;= \frac{1}{{{{\sin }^2}\theta\, {{\cos }^2}\theta }}\\ &\qquad\;= \frac{1}{{{{\sin }^2}\theta\; (1 - {{\sin }^2}\theta )}}\\ &\qquad\;= \frac{1}{{{{\sin }^2}\theta - {{\sin }^4}\theta }} \;= RHS\end{align}\], \[\frac{{1 - \cos \theta }}{{1 + \cos \theta }} = {\left( {\text{cosec}\,\theta - \cot \theta } \right)^2}\], Solution: Let’s start with the right side, \[\begin{align}&RHS = {\left( {\frac{1}{{\sin \theta }} - \frac{{\cos \theta }}{{\sin \theta }}} \right)^2}\\ &\qquad\;\;= {\left( {\frac{{1 - \cos \theta }}{{\sin \theta }}} \right)^2}\\ &\qquad\;\;= \frac{{{{\left( {1 - \cos \theta } \right)}^2}}}{{{{\sin }^2}\theta }}\\ &\qquad\;\;= \frac{{{{\left( {1 - \cos \theta } \right)}^2}}}{{1 - {{\cos }^2}\theta }}\\ &\qquad\;\;= \frac{{{{\left( {1 - \cos \theta } \right)}^2}}}{{(1 + \cos \theta )(1 - \cos \theta )}}\\ &\qquad\;\;= \frac{{1 - \cos \theta }}{{1 + \cos \theta }} = LHS\end{align}\].
