tan (arccos (4 x))

\frac{1 - 16 x ^{2}}{4 x}

Solution steps

tan (arccos (4 x))

Use the following identity:

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

= \frac{1 - ( 4 x ) ^{2}}{4 x}

1 - (4 x)^{2} = 1 - 16 x^{2}

= \frac{1 - 16 x ^{2}}{4 x}

tan (\frac{π}{4} + \frac{x}{2})

sin^{4} (- cos^{4} (x))

- sin (- 3 x)

sin (arcsec (\frac{x}{3}))

1 - cos^{2} (θ)
