**Solve by using Variation of Parameters y'' + y = sin(x**

Basic Trigonometry The following instructions operate with angles and trigonometric functions. There are six basic trigonometric functions, which are most simply introduced by considering a right-angled triangle, one of whose other angles is x as in the figure below:... Solve sin(x) = y for x. Case 1: -1 ≤y≤ 1, that is, the value of y is between -1 and 1, so there is a solution. The set of all solutions to sin(x) = y is. x = sin-1 (y) + 2kπ and x = −sin-1 (y) + (2k+1)π, where k can be any integer; that is, the solutions for x consist of sin-1 (y) plus all even multiples of π, together with minus sin-1 (y) plus all odd multiples of π. Case 2: -1 > y

OK, so why find the derivative y’ = −x/y ? Well, for example, we can find the slope of a tangent line. Example: what is the slope of a circle centered at the origin with a radius of 5 at the point (3,4)?

- This applies only when we have things like sin(x) or tan(x) + 2 for example. If we have multiples, such as cos(2x), then we also multiply up the possible number of solutions. In "general", as a rule of thumb, expect the following, within any 360 degree range:
