Question

sin 2 theta is equal to 2 sin theta cos theta is true when theta is equal to

Answer 1

Answer:

well I don't know this, I hate maths....btw hi ar.my

Answer 2

Step-by-step explanation:

Given that sinθ+cosθ=1

now squaring both side we have

(sinθ+cosθ)

2

=1

2

sin

2

θ+cos

2

θ+2sinθcosθ=1

1+2sinθcosθ=1 (sin

2

θ+cos

2

θ=1)

2sinθcosθ=0

sin2θ=0 (sin2θ=2sinθcosθ)
