4. Take out the first tile. 1  Scrape out the grout from around the first tile you're removing. 2  Use a utility knife to scrape in between the tiles. 3  The first tile is always the hardest to remove since there's no point of entry. 4  Angle a putty knife into the crack where the grout was removed and wedge it underneath a tile.
cosh (mathematical function), hyperbolic cosine, a mathematical function with notation cosh(x) -COSH, a representation of the thiocarboxylic acid functional group in chemistry Chlorpromazine, an antipsychotic drug
`(d(sin\ x))/(dx)=cos\ x` `(d(cos\ x))/dx=-sin\ x` `(d(tan\ x))/(dx)=sec^2x`. The derivative of sin x is cos x, The derivative of cos x is âsin x (note the negative sign!) and The derivative of tan x is sec2x. `(d(sin\ u))/(dx)=cos\ u(du)/(dx)` `(d(cos\ u))/dx=-sin\ u(du)/(dx)` `(d(tan\ u))/(dx)=sec^2u(du)/(dx)`. `y=(2x+3)/(sin\ 4x)`. x cos 2y + sin x cos y = 1.
