Answer 1

$\huge {{\bf { \: question }}}\\\huge\boxed{\underline{\bf { {cos}^{2} θ + \frac{1}{1 + {cot}^{2} θ} = 1 }}}$

Step-by-step explanation:

$\huge\sf\mathbb\color{yellow} {given}$

$\huge\sf\mathbb\color{blue} { {cos}^{2}θ + \frac{1}{1 + {cot}^{2} }θ = 1 }$

$\huge\sf\mathbb\color{blue} {LHS = {cos}^{2} θ + \frac{1}{ 1 + {cot}^{2} θ} }$

$\huge\sf\mathbb\color{blue} { = {cos}^{2} θ + \frac{1}{cose {c}^{2} θ} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: [ 1 + {cot}^{2}θ = {cosec}^{2} θ ]$

$\huge\sf\mathbb\color{blue} { = {cos}^{2} θ + {sin}^{2} θ = 1 }\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \ \: [ \frac{1}{cosecθ} = sinθ]$

$\huge\sf\mathbb\color{blue} {LHS = {cos}^{2} Θ + {sin}^{2} Θ = 1 =RHS }$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \huge\sf\mathbb\color{red} {hence \:proved }$
