Question

If tan theta =1,then the value of sin 2 theta=​

Answer 1

Answer:

1

Step-by-step explanation:

Tan theta = 1

Tan theta = Tan 45

theta = 45

Sin 2 Theta= Sin 2(45)

= Sin90

=1

Answer 2

Answer:

[see the attachment]

we can solve it easily by applying the formula of Sin 2 theta in terms of of tan theta that is

$\sin(2 \: \theta) \:= \frac{ 2\tan( \theta) }{1 + {tan}^{2} \theta}$

flash value of tan theta is equals to 1 so by applying this formula we will get the value of sin 2 theta is equals to 1
