Question

What is ms method and direct integration menthod?

Answer 1

Mass spectrometry (MS) is an analytical technique that ionizes chemical species and sorts the ions based on their mass-to-charge ratio. In simpler terms, a mass spectrummeasures the masses within a sample. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.




direct integration method....:-
The simplest differential equations to solve are those in the form of dydt=f(t). These differential equations can be solved by directly integrating both sides to get that for any antiderivative F and for C as a constant we have that:

(1)

∫dydtdt=∫f(t)dty=F(t)+C

For example, suppose that we wanted to solve the differential equation dydt=t2+cos2t. Then we have that for C as a constant:

(2)

∫dydtdt=∫t2+cos2tdty=t33+sin2t+C
