prove that: ln[RX]_{o}/[RX]{_{t=kt is equal to log10[RX]_t=-(kt/2.303)+log10[RX]_o Remember that ln(a/b)=ln(a)-ln(b) and ln)x)=2.303log(x) Using Euler's identity, rewrite the first four 2-D rotational wavefunctions in terms of...
If sin(x) = 5/6 and sin(y) = 3/5, find sin(x + y)? Solve the equation \sin (x)=0.65 in the interval [\frac{9}{2} \pi, \frac{3}{2} \pi]. (Clearly explain where and how you use the identity \sin(x) = -\sin(x+\pi), and give all possible solutions.) ...

We can use the identity a2−b2=(a−b)(a+b) to rewrite cos4x−sin4x:cos4x−sin4x=(cos2x−sin2x)(cos2x+sin2x)Since cos2x+sin2x=1, this simplifies to:cos4x−sin4x=cos2x−sin2x=cos2xThus, we can rewrite the original equation as:cos2x+cos2x+α2+α=0This simplifies ...
