## Trigonometry (10th Edition)

$$\sin x+2=3$$ 1) Decide whether the equation is linear or quadratic in form Here we see that $\sin x$ is in first degree, so the equation is linear in form. 2) Count the number of trigonometric functions in the equation Only $\sin x$ is present, so the equation has only one trigonometric function. 3) Since the equation is linear in form and has only one trigonometric function, we solve the equation normally
