Solution: QUESTION: 5 then the value of cos 2θ is

Solution:  QUESTION: 6

Find tan θ/3

Solution:
QUESTION: 7

The value of tan Solution: QUESTION: 8

When sinθ + cosθ = 1, then the value of sin2θ is

Solution:

Squaring on both sides,you get sin2x + 2sinxcosx + cos2x = 1

which gives 1 + 2sinxcosx = 1 {since sin2x +cos2x = 1 for all x}

which means,2sinxcosx =0

which means either sinx =0 or cosx=0

so,the general solution is that for sinx=0 union cosx=0

QUESTION: 9
