(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

determin the dimensions of [tex]\alpha[/tex] in the following

a)Sin([tex]\alpha[/tex]X[tex]^{}2[/tex]) (alpha* X squared) (X is a distance)

b)10^{[tex]\alpha[/tex]t3}

c)cot([tex]\alpha[/tex]X^{2}/R) (R is a radius)

d)e^{(hf/[tex]\alpha[/tex]T}- 1 (h is plancks constant with units J*s) ( f is frequency

2. Relevant equations

3. The attempt at a solution

so are these all supposed to be dimensionless?

attempt at a: [L^{2}[tex]\alpha[/tex] ] = 1 therefore [tex]\alpha[/tex]= [1/L^{2}] (where L is length)

id appreciate some help :)
