limit as x approaches 1-of sech^2(x-1)

x \to 1 - lim (sech^{2} (x - 1))

1

Solution steps

x \to 1 - lim (sech^{2} (x - 1))

Plug in the value

x = 1

= sech^{2} (1 - 1)

Simplify

sech^{2} (1 - 1) : 1

= 1

\frac{\partial}{\partial y} (2 x y^{3} + 4)

\int 12 + 4 t^{2} d t

y^{^{''}} - 4 y^{^{'}} - 5 y = 0, y (1) = 0, y^{^{'}} (1) = 9

f (x) = 7 - 6 x, at x = 1

y^{2} \frac{d y}{d x} = y^{3} - x^{3}
