# Sum and Difference Trigonometric Formulas

\[ \large \dfrac{\cot^375^{\circ}+\tan^375^{\circ}}{\cot75^{\circ}+\tan75^{\circ}} = \ ? \]

\[\large \dfrac{\sin^2 (3A)}{\sin^2 (A)}-\dfrac{\cos^2 (3A)}{\cos^2 (A)}=2 \]

\[ \implies \large \cos (2A)= \ ? \]

The equation above is true for positive integers \(a,b,\) and \(c.\) What is the value of \(a+b+c?\)
