tan (arccos (7 x))

\frac{1 - 49 x ^{2}}{7 x}

Solution steps

tan (arccos (7 x))

Use the following identity:

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

= \frac{1 - ( 7 x ) ^{2}}{7 x}

1 - (7 x)^{2} = 1 - 49 x^{2}

= \frac{1 - 49 x ^{2}}{7 x}

cot (arccos (u))

cot (4 5^{\circ} + x)

cos (arcsin (20 x))

sin (18 0^{\circ} + a)

3 sin (2 x + \frac{π}{3})
