Question
For each of the following equations, solve for (a) all degree solutions and (b) $\theta$ if $0^{\circ} \leq \theta<360^{\circ}$ Use a calculator to approximate all answers to the nearest tenth of a degree.$$2 \cos \theta-5=3 \cos \theta-2$$
Step 1
We can do this by moving all terms involving $\theta$ to one side of the equation and the constants to the other side. This gives us: \[2 \cos \theta - 3 \cos \theta = 2 - 5\] Show more…
