Answer:

we know that cotθ is

 \frac{1}{tanθ}

Step-by-step explanation:

so we can write cotx - tanx as :

 \frac{1}{tanx} \:  - tanx

 \frac{1 - tan {}^{2}x }{tan x\: }

(LCM taken)

We know that tanθ =

 \frac{p}{b}

where P = perpendicular

B = base

 \frac{1  - \frac{p {}^{2} }{b {}^{2} } }{ \frac{p}{b} }

 \frac{b {}^{2} - p {}^{2}  }{b {}^{2} } \div  \frac{p}{b}

 \frac{ {b}^{2} -  \:  {p}^{2} }{ {b}^{2} }  \times  \frac{b}{p}

 \frac{ {b}^{2}  -   \: {p \:}^{2} }{bp}

then using a² - b² = (a+b)(a-b)

 \frac{ \: (b+p)(b-p) \: }{pb}

identity

we can get the simplest form :
