Question

If root 3sin theta=cos theta find the value of 3cos square theta +2cos theta divided by 3cos theta +1

Answer 1

Answer:

Step-by-step explanation:

root3 sin theta = cos theta

root 3= cos theta/sintheta

tantheta= root 3

tan 60= root 3

3 cos2 60 + 2 cos 60/3 cos60 +1

3 {1/2}2 + 2 1/2 / 3 {1/2} +1

3{1/4} + 1 /3/2+1

3/4+1 +3/2+1

3+4/4  + 3+2/2

7/4+5/2

7/4+10/4

17/4
