Splet20. feb. 2024 · Part (i) is essentially integration in spherical coordinates. If n = 2, spherical coordinates are called polar coordinates. In general, a point x ∈ R n ∖ 0 can be represented uniquely as x = r ω, where r > 0 and ω ∈ S n − 1 . These two "coordinates" ( r, ω) are found simply as r = x and ω = x / x . These are the spherical coordinates. Splet15. dec. 2024 · 1. Just pretend that y is a constant and solve the equation as if z is a function of x alone. Then the solution is A cos x + B sin x where A and B are constants. … how to care for a pressure sore on a buttock

Just pretend that y is a constant and solve the equation as if z is a function of x alone. Then the solution is A cos x + B sin x where A and B are constants. Now if you consider y as a variable then you have to replace A and B by functions of y. The initial conditions easily give you A = e y and B = 1 so the solution is e y cos x + sin x.
