As a result, we can now simplify the complex side of the trigonometric equation easily. Answer and Explanation: $$\begin{align} \frac{\cot x}{\csc x}-\frac{\csc x}{\cot x}&=-\sin x \tan x\[0.3cm] \dfrac{\dfrac{\cos x}{\sin x}}{ \dfrac{1}...
Verify that the equation is an identity. {eq}\cot x \left [ \cot (-x) + \tan (-x) \right ] = - \csc^2 x {/eq} Trigonometric Identity: In trigonometry, we deal with angles and the length of the side of the triangles. According to the sides, we get three...
