Question

all solutions to 3 sec x - 2 = 0

Answer 1

\[\large \begin{align}
3\sec(x)-2 &= 0\\
3\sec(x)&=2\\\sec(x)&=\frac{2}{3}
\end{align}\]

Answer 2

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

Answer 3

\[\large \frac{1}{\cos(x)}=\frac{2}{3}\\\large \cos(x)=\frac{1}{\frac{2}{3}}=1(\frac{3}{2})=\frac{3}{2}\]

Answer 4

\(\large x = \arccos\frac{3}{2}\)
