Answer 2

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\put(1,1.2){\line(1,0){6.5}}\end{picture}$

❏ Question:-

Find the value of ,

$\implies\sf{ \ \ {\dfrac{\sin x+cos x}{sun x - \cos x}}}$

when , $\sf{\tan x= \frac{3}{4}}$

❏ Solution:-

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\put(1,1.2){\line(1,0){6.5}}\end{picture}$

$\implies\sf{ \ \ {\dfrac{\sin x+cos x}{sun x - \cos x}}}$

( divided by cos x on both )

$\implies\sf{ \ \ {\dfrac{\dfrac{\sin x+cos x}{\cos x}}{\dfrac{sun x - \cos x}{\cos x}}}}$

$\implies\sf{ \ \ {\dfrac{\dfrac{\sin x}{\cos x}+\dfrac{cos x}{\cos x}}{\dfrac{sin x }{\cos x}- \dfrac{\cos x}{\cos x}}}}$

$\implies\sf{ \ \ {\dfrac{\tan x+1}{\tan x-1}}}$

$\implies\sf{ \ \ {\dfrac{\dfrac{3}{4}+1}{\dfrac{3}{4}-1}}}$

$\implies\sf{ \ \ {\dfrac{\dfrac{3+4}{4}}{\dfrac{3-4}{4}}}}$

$\implies\sf{ \ \ {\dfrac{\dfrac{7}{4}}{\dfrac{-1}{4}}}}$

$\implies\sf{ -7}$
