siirtymämuunnos
Siirtymämuunnos, known in English as the change of variables or substitution method, is a technique used in mathematics, particularly in calculus and differential equations, to simplify complex problems by transforming them into simpler, more manageable forms. The core idea is to replace the original variables with new ones in such a way that the resulting expression or equation becomes easier to solve.
In integration, the change of variables often involves substituting a part of the integrand with a new
Similarly, in differential equations, a change of variables can transform a complex equation into a simpler
