If $\operatorname{cosec} A - \cot A = \dfrac{4}{3}$ , then $\operatorname{cosec} A + \cot A = ?$

a $\dfrac{3}{4}$
b $\dfrac{4}{3}$
c $1$
d $-\dfrac{3}{4}$

ব্যাখ্যা

Because $(\operatorname{cosec} A-\cot A)(\operatorname{cosec} A+\cot A)=\operatorname{cosec}^2 A-\cot^2 A=1$ , the two expressions are reciprocals. Hence $\operatorname{cosec} A+\cot A=\dfrac{1}{4/3}=\dfrac34$ .
