AAbhi can't understand How (cosbx+isinbx) changed to e^ibx

e^(I.theta)=cos(theta)+isin(theta)

Yeah Euler theorem

SSirLancelotDuLac e^(I.theta)=cos(theta)+isin(theta)

Never heard it weird which chapter it comes in ?

Oh. Welp there were some things that could help in simplification and stuff for integration:/

SirLancelotDuLac•6/17/25, 9:52 AM

Like that e^(ax)sin(bx) thing.

SirLancelotDuLac•6/17/25, 9:53 AM

Or sinⁿx

Yeah allen does this they teach complex and even pnc in 12th only
