Question

if theta=45 then find tan^2 theta+1/sin^2 theta=?

Answer 1

 solution

given that Ф=45

to compute tan²Ф+1/sin²Ф

⇒ = tan²45+1/sin²45

⇒ = 1² + 1÷(1/√2)²

⇒ = 1 + 1÷(1/2)

⇒ = 1 + 1×2/1

⇒ = 1+2

 =3

Answer 2

Answer:

Step-by-step explanation:

solution

given that Ф=45

to compute tan²Ф+1/sin²Ф

⇒ = tan²45+1/sin²45

⇒ = 1² + 1÷(1/√2)²

⇒ = 1 + 1÷(1/2)

⇒ = 1 + 1×2/1

⇒ = 1+2
