hi everyone
what is the definition of the tangent
straight line to the curve without relying
to the derivitve
because the derivative is the slope
and thanx for all
Q1)find tow power series solutions of the
given D.E about x=0
y^(′′) −2xy^′ +y=0
Q2)use the power series method to solve the
given intial value problem
y^(′′) −2xy^′ +8y=0
y(0)=3y^′ (0)=0
