1) This equation is a trigonometric identity known as the Pythagorean identity. It states that cos^2(x) = 1 + sin^2(x) for any angle x.
2) The equation 4cos(x) = 3 can be solved by dividing both sides by 4 to isolate cos(x). This gives us cos(x) = 3/4. The solution for x will depend on the range of angles you are considering (typically, angles are measured in radians or degrees).
