The natural abundances of chlorine’s two major isotopes are 35Cl (75.5%) and 37Cl (24.5%)

The natural abundances of chlorine’s two major isotopes are 35Cl (75.5%) and 37Cl (24.5%). If the mass spectrum of chlorobenzene contains a peak at m/z 114 with an abundance of 5.0%, calculate the percent abundance of the peak at m/z 12. The Correct Answer and Explanation is: To calculate the percent abundance of the peak

sec(pi/2-u)= ?

sec(pi/2-u)= ? The Correct Answer and Explanation is: To find the value of:sec⁡(π2−u)\sec\left(\frac{\pi}{2} – u\right)sec(2π​−u) we use a trigonometric identity involving co-function relationships. Co-function Identity: sec⁡(π2−u)=csc⁡(u)\sec\left(\frac{\pi}{2} – u\right) = \csc(u)sec(2π​−u)=csc(u) This identity comes from the general co-function rules in trigonometry, which relate the trigonometric function of an angle to the co-function of its complement. In
