Question

If 2 + sec 0 = 4, then 0 =

Answer 1

Step-by-step explanation:

tanθ+secθ=4⇒

cosθ

1+sinθ

=4⇒

4

1+sinθ

=cosθ

Also, we know that,

cos

2

θ=1−sin

2

θ⇒(

4

1+sinθ

)

2

=1−sin

2

θ⇒1+sin

2

θ+2sinθ=16−16sin

2

θ⇒17sin

2

θ+2sinθ−15=0

⇒(sinθ+1)(17sinθ−15)=0⇒sinθ=

17

15

or −1

Therefore, Answer is

17

15
