Question

If θ = 45°, then what is the value of 2 sec2θ + 3 cosec2θ
​

Answer 1

Answer:

3+2(infinity)

Step-by-step explanation:

• here θ = 45° then

• sec2θ =sec 2(45°)=sec90°=infinity

• in the same way csc2θ=csc 2(45°)=csc90°=1

• according to question 2 sec2θ + 3 cosec2θ

• equals to 2(infinity)+3(1)

I hope this helps you

Answer 2

Answer:

Step-by-step explanation:

3+2(infinity)

Step-by-step explanation:

here θ = 45° then

sec2θ =sec 2(45°)=sec90°=infinity

in the same way csc2θ=csc 2(45°)=csc90°=1

according to question 2 sec2θ + 3 cosec2θ

equals to 2(infinity)+3(1)
