Question

If sin theta=cos theta,then find the value of 2tan theta+cos theta

Answer 1

Answer:

Step-by-step explanation:

Let theta =a(for convenience in typing)

sin a=cos a

sin a/cos a=1

tan a=1

a=45 degrees

2tan a+ cos a= 2tan 45+ cos 45

                      =2+1/sqrt(2)

                      =[2sqrt(2)+1]/2
