Question

Use trigonometric identities, algebraic methods, and inverse trigonometric functions, as necessary, to solve the following trigonometric equation on the interval [0, 27).Round your answer to four decimal places, if necessary. If there is no solution, indicate "No Solution."Scos(x) - 5 = 0

Answer 1

we have the function

`5\cos x-5=0`

Rewrite

`\begin{gathered} 5\cos x=5 \\ \cos x=(5)/(5) \\ \cos x=1 \end{gathered}`

The domain for x is the given interval [0,2pi) ----> 2pi is not included

the values of x are

x=0 radians

The solution is x=0
