Solve the differential equation y''=ysin^2x using variation of parameters.

the solution is 12x-6y

step-by-step explanation:

abc

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

1. perpendicular

2. parallel

3. perpendicular
