      Example 1. Solve y000= 0. Solution: p(r) = r3 implies 1 is a base atom and then 1, x, x2 are solution atoms. They are independent, hence form a basis for the 3-dimensional solution space.Then y= c 1 + c 2x+ c 3x2. Example 2. Solve y00+ 4y= 0. Solution: p(r) = r2 + 4 implies base atoms cos2xand sin2x.They are a basis for the 2-dimensional solution space with y= c 1 cos2x+ c 2 sin2x.

      We have, cos2x = cos2x - sin2x = (1 - sin2x) - sin2x [Because cos2x + sin2x = 1 ⇒ cos2x = 1 - sin2x] = 1 - sin2x - sin2x = 1 - 2sin2x Hence, we have cos2x = 1 - 2sin2x in terms of sin x. Cos2x In Terms of cos x Just like we derived cos2x = 1 - 2sin2x, we will derive cos2x in terms of cos x, that is, cos2x = 2cos2x - 1. We will use the ...
