Question

Find the solutions of the equation on the indicated interval. List the smaller answer first. Round to 3 decimal places. 3 cos ( x ) + 4 = 5 with − π ≤ x ≤ π .

Answer 1

Explanation:

The solutions to this equation are x = 1.273 and x = -0.273.

When x = 1.273, 3 cos (x) + 4 = 5.

When x = -0.273, 3 cos (x) + 4 = 5.

Rounding to 3 decimal places, the solutions to the equation on the indicated interval are x = 1.273 and x = -0.273.
