Answer to: Use a half-angle identity to find the exact value of the trigonometric expression. Rationalize the denominator insie the square root. ...
A half angle refers to half the value of an angle that is known or currently being looked at. It doesn't have a constant value. It's just half the value of some angle. What is the Half Angle Formula? Half-angle identitiesare used to find the value (or exact value) of thesine, ...

We immediately find that the deformed thickness h=H/λ. Whenever a quantity in the substrate and in the film take the same value, we will discard the upper hat to denote both. For the director, we have (2.6)n0=cosθ0E1+sinθ0E2,n̄=cosθ̄E1+sinθ̄E2,where θ0 and θ̄...

By Lagrange’s identity |a|2|b|2=|⟨a,b⟩|2+|a∧b|2∀a,b∈R3, (B.5) we see that for u(x)∈H˙12(R;S2), ||∇|1/2u(x)|⩽|u(x)⋅|∇|1/2u(x)|+|u(x)∧|∇|1/2u(x)|. In order to exploit this pointwise inequality for a regularity bounds for (B...
