simplify cot(arccos(x/(17)))

simplify

cot (arccos (\frac{x}{17}))

\frac{x 289 - x ^{2}}{289 - x ^{2}}

Solution steps

cot (arccos (\frac{x}{17}))

Use the following identity:

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

= \frac{( \frac{x}{17} ) 1 - ( \frac{x}{17} ) ^{2}}{1 - ( \frac{x}{17} ) ^{2}}

Simplify

= \frac{x 289 - x ^{2}}{289 - x ^{2}}

cos (n π^{1})

\frac{tan ( - x )}{tan ( x )}

sin (θ) + sin (θ + 2 π) + sin (θ + 4 π)

sec (\frac{π}{2} + a)

f (x) = 3 x sec (7 0^{\circ}) - 2
