Question

(1+tanQ+secQ) (1+cotQ-cosecQ)​

Answer 1

Answer:

2

Step-by-step explanation:

(1 + tanQ + secQ)  (1 + cotQ - cosecQ)​

= (1+$\frac{sinQ}{cosQ}$+$\frac{1}{cosQ}$) (1+$\frac{cosQ}{sinQ}$-$\frac{1}{sinQ}$)​

= (1+$\frac{sinQ}{cosQ}$+$\frac{1}{cosQ}$) (1+$\frac{cosQ}{sinQ}$-$\frac{1}{sinQ}$)​

= (1+$\frac{sinQ}{cosQ}$+$\frac{1}{cosQ}$) (1+$\frac{cosQ}{sinQ}$-$\frac{1}{sinQ}$)​

= (1+$\frac{sinQ+1}{cosQ}$) (1+$\frac{cosQ-1}{sinQ}$)​

= ($\frac{cosQ+sinQ+1}{cosQ}$) ($\frac{sinQ+cosQ-1}{sinQ}$)​

= $\frac{(cosQ+sinQ)^2-1^2)}{sinQcosQ}$

= $\frac{sin^2Q+cos^2Q+2sinQcosQ-1}{sinQcosQ}$

= $\frac{1+2sinQcosQ-1}{sinQcosQ}$

= $\frac{2sinQcosQ}{sinQcosQ}$

= 2
