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



★REQUIRED QUALITY ANSWER★​

Answer 1

Answer:

given trigonometric expression is 10.

Step-by-step explanation:

We have been given that

θ=45

We have to find the value of the trigonometric expression

2csc^2 θ+3sec² θ

Substitute the value of Ф

2csc²(45°)+3sec²(45°)

Evaluating the trigonometric values at Ф = 45° and then simplify the expression

2(√2²)+3(√2²)

=2.2+3.2

=4+6

=10

Therefore, the value of the given trigonometric expression is 10.
