Question

If 3 sin theta -4 cos theta =0,then find the value of sin theta -cos theta/ sin theta +cos theta

Answer 1

for better understanding i am using A in place of thetha

now,

3sinA-4cosA=0

3sinA=4cosA  

sinA=4/3cosA                 .....1

put eq 1 in sinA-cosA/sinA+cosA

=4/3cosA-cosA)/4/3cosA+cosA

=1/5
