    Calculus Book for complementing differential equations

    That book is ~100 old and is barely readable. A modern alternative would be Elementary Euclidean Geometry by C G Gibson.

    I saw the whole eclipse except a bit of beginning but I didn't any blood or red colour. It was all white for me.

    I Understanding an integral

    Unless I made a sign error I think the best you can do is $$ \int \frac{d^3\phi}{dx^3} \psi dx + \int \dfrac{d^3\psi}{dx^3} \phi dx = \psi \dfrac{d^2 \phi}{ dx^2} - \dfrac{d\psi}{dx} \dfrac{d \phi}{ dx} + \dfrac{d^2\psi}{dx^2} \phi $$

    I Understanding an integral

    Meh ... my try : $$\int \frac{d^3\phi}{dx^3} \psi dx = \psi \dfrac{d^2 \phi}{ dx^2} - \int \dfrac{d\psi}{dx} \dfrac{d^2 \phi}{ dx^2} dx = \psi \dfrac{d^2 \phi}{ dx^2} - \left( \dfrac{d\psi}{dx} \dfrac{d \phi}{ dx}-\int \dfrac{d^2\psi}{dx^2} \dfrac{d \phi}{ dx} dx\right) \\= \psi \dfrac{d^2...

    NaOH Vs C2H5-OH

    ##C_2H_5OH+H_2O--->C_2H_6O+H_2O## is wrong. Ethanol does (partially)dissociate into hydroxyl group and alkyl group, just that this dissociation does not happen in plain water. In nucleophilic substitution reactions (ethanol mainly undergoes SN2) -OH of ethanol is partially dissociated from...
