simplify arccos(1/(cos(5θ)))

simplify

arccos (\frac{1}{cos ( 5 θ )})

arccos (sec (5 θ))

Solution steps

arccos (\frac{1}{cos ( 5 θ )})

Use the basic trigonometric identity:

\frac{1}{cos ( x )} = sec (x)

= arccos (sec (5 θ))

cos (t + \frac{3 π}{2}) - 1

2 cos (6 x + \frac{π}{2})

a r cos (\frac{2 - 3}{2} - 1)

3 sin (2 x + \frac{π}{4})

sin (x - \frac{π}{5}) + 3
