\huge\fbox{\purple{tan \ x \ =  4/3}}

\huge\fbox{\purple{sec \ x \ = \ 5/3 }}

\huge\fbox{\purple{cosec \ x \ =  5/4}}

Step-by-step explanation:

Question:-

If 3 sin theta -4 cos theta = 0, then find the values of tan theta ,sec theta and cosec theta.

Given:-

  • 3 sin x - 4 cos x = 0

To find:-

  • tan x

  • sec x

  • cosec x

Required Solution:-

Given that 3 sin x - 4 cos x = 0

: ➝ 3 sin x = 4 cos x. [ by moving (- 4 cos x) to RHS]

 =  >  \frac{sin \: x}{cos \: x}  =  \frac{4}{3}

 =  > tan \: x =  \frac{4}{3}

[As tan x = sin x/cos x]

\huge\mathcal{\green{Now,}}

We have

: ➝ 1 + tan^2x = sec^2 x

 =  > \:  {sec}^{2} x = 1 +  ({ \frac{4}{3} )}^{2}

 =  >  {sec}^{2} x = 1 +  \frac{16}{9}

 =  >  {sec}^{2} x =  \frac{9 + 16}{9}  =  \frac{25}{9}

 =  > sec \: x =  \sqrt{ \frac{25}{9} }

 =  > sec \: x =  \frac{5}{3}

\huge\mathcal{\green{Now,}}

cot \: x =  \frac{1}{tan \: x}

\huge\mathcal{\green{Therefore,}}

cot \: x =  \frac{3}{4}

\huge\mathcal{\green{Now,}}

We have

: ➝ cosec^2x = cot^2 x + 1

 =  >  {cosec}^{2} x = ( { \frac{3}{4} )}^{2}  + 1

 =  >  {cosec }^{2} x =  \frac{9}{16}  + 1

 =  >  {cosec}^{2} x =  \frac{9 + 16}{16}  =  \frac{25}{16}

 =  > cosec \: x =  \sqrt{ \frac{25}{16} }  =  \frac{5}{4}
