Evaluate each of the following:tan2 30° + tan2 60° + tan2 45°

1.	Evaluate each of the following:tan2 30° + tan2 60° + tan2 45°
Answer» tan² 30° + tan² 60° + tan² 45° = \((\frac{1}{\sqrt3})^2\) + \((\sqrt3)^2\) + (1)² ^{= \(\frac{1}3+3+1\) = \(\frac{13}3\)}

Answer»

tan² 30° + tan² 60° + tan² 45°

= \((\frac{1}{\sqrt3})^2\) + \((\sqrt3)^2\) + (1)²

^{= \(\frac{1}3+3+1\) = \(\frac{13}3\)}
