Question
Find all solutions in the interval from 0 < theta
![The equation presented is:
\[ 4 \cos \theta - 2 \sec \theta = 0 \]
This trigonometric equation involves the cosine and secant functions, where:
- \(\cos \theta\) represents the cosine of angle \(\theta\).
- \(\sec \theta\) is the secant of \(\theta\), which is the reciprocal of the cosine, defined as \(\sec \theta = \frac{1}{\cos \theta}\).
To solve this equation, you can manipulate it to find the values of \(\theta\) that satisfy the equation. This typically involves finding a common expression or simplifying using trigonometric identities.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F838d6200-dd8b-4de4-b6ca-eaa9f9f43bab%2F4896871b-e8f7-4c49-b34e-0b4ea7ceaade%2F6vycoh_processed.jpeg&w=3840&q=75)
