Question

with the above diagram answer the following secant of theta is equal to y by x when tita doesn't belong to
1 . { π/ 2 , 3π/2 }
2. {π/4 }
3. {π,2π}
4.{ π/6}
Pls answer in proper language then i will mark you as brilliant​

Answer 1

Answer:

Given that x=secθ+tanθ

y=secθ−tanθ

As we know that

sec

2

θ−tan

2

θ=1

⟹(secθ+tanθ)(secθ−tanθ)=1

⟹xy=1

Answer 2

Answer:

Answers: tan 45° = 1; cos 45° = 1/√2 or √2/2; sin 90° = 1; cos 30° = √3/2; sin 30° = 1/2; cos 90° = 0. 3 Find sin(π/4), cos(π/6), tan(π/3).
