WebMar 31, 2024 · tan θ is a commonly used trigonometric function along with other 5 functions. tan θ is also called as law of tangent. The tangent formula for a right-angled triangle can be defined as the ratio of the opposite side of a triangle to the adjacent side. It can also be represented as a ratio of the sine of the angle to the cosine of the angle. WebSpherical coordinates are useful in analyzing systems that are symmetrical about a point. For example a sphere that has the cartesian equation x 2 + y 2 + z 2 = R 2 has the very simple equation r = R in spherical coordinates. Spherical coordinates are the natural coordinates for physical situations where there is spherical symmetry (e.g. atoms).
For a given polymer-solvent pair, the theta condition is satisfied at a certain temperature, called the theta (θ) temperature or theta point. A solvent at this temperature is called a theta solvent. In general, measurements of the properties of polymer solutions depend on the solvent. See more In a polymer solution, a theta solvent (or θ solvent) is a solvent in which polymer coils act like ideal chains, assuming exactly their random walk coil dimensions. Therefore, the Mark–Houwink equation exponent is $${\displaystyle 1/2}$$ in … See more • Flory–Huggins solution theory See more The conformation assumed by a polymer chain in dilute solution can be modeled as a random walk of monomer subunits using a See more Thermodynamically, the excess chemical potential of mixing between a theta solvent and a polymer is zero. Equivalently, the enthalpy of mixing is zero, making the solution See more WebTools.

WebNov 5, 2024 · is an eigenfunction of the operator ˆT, defined in Equation 11.3.3. Solution The 1s orbital depends on r only, and therefore the derivatives with respect to θ and ϕ are zero (this will be true for all the s-orbitals). Therefore, Equation 11.3.3 reduces to: ˆT = − ℏ2 2m ( 1 r2 ∂ ∂r(r2 ∂ ∂r))
