simplify tan(arccos(x/(14)))

simplify

tan (arccos (\frac{x}{14}))

\frac{196 - x ^{2}}{x}

Solution steps

tan (arccos (\frac{x}{14}))

Use the following identity:

tan (arccos (x)) = \frac{1 - x ^{2}}{x}

= \frac{1 - ( \frac{x}{14} ) ^{2}}{( \frac{x}{14} )}

Simplify

= \frac{196 - x ^{2}}{x}

sin (sin (x + 2 π))

2 cos (x) + 7 cos (4 5^{\circ} - x)

sin (x - \frac{5 π}{3})

cos (2 x + 3 0^{\circ})

cos (arctan (x \frac{1}{3}))
