Question

Tan 2thita×tan thita = 1 , thita ka boyapk man ?

Answer 1

Step-by-step explanation:

We know that

tan

θ

=

sin

θ

cos

θ

, so we know that

sin

θ

=

a

and

cos

θ

=

b

a

sin

θ

−

b

cos

θ

a

sin

θ

+

b

cos

θ

=

a

(

a

)

−

b

(

b

)

a

(

a

)

+

b

(

b

)

This can be written as

a

2

−

b

2

a

2

+

b

2

.

Hopefully this helps!

Answer 2

Step-by-step explanation:

im cosindering theta as x for ease

do cope up

so

tan2x is 2tanx /1-tansquare x

thus

2tansquarex/1-tansquarex = 1

2tansquare x = 1 -tansquare x

3tansquarex=1

tansquare x =. 1 / 3

tanx = 1 / √3

so x = 30 °
