Answer 1

Answer:

2 Cosec ∅

Step-by-step explanation:

$\frac{sin∅}{1+cos∅}$ + $\frac{1+Cos∅}{Sin∅}$

Taking LCM:

$\frac{(Sin∅)^{2} + (1+Cos∅)^{2}}{(Sin∅)(1+Cos∅)}$

$\frac{Sin^2∅ + Cos^2∅ + 1 + 2Cos∅}{(Sin∅)(1+Cos∅)}$

Using $Sin^2∅ + Cos^2∅ = 1$

$\frac{1+1+2Cos∅}{(Sin∅)(1+Cos∅)}$

$\frac{2+2Cos∅}{(Sin∅)(1+Cos∅)}$

$\frac{1(1+Cos∅)}{(Sin∅)(1+Cos∅)}$

$\frac{2}{(Sin∅)}$

== 2 Cosec∅
