Question

If theta is equal to 45° what is the value of 2 sec^2 theta +3 cosec^2 theta

Answer 1

2sec^2 theta +3 cosec^2 theta = ?

we know that sec 45 = root 2 & cosec 45 = root2

so by putting values we get

2 × sec ^ 2 (45) + 3 × cosec ^ 2 (45)

= 2 × 2 + 3 × 2 = 6

so , 2sec^2 theta +3 cosec^2 theta = 6

Answer 2

Answer:

2sec^2 theta +3 cosec^2 theta = ?

we know that sec 45 = root 2 & cosec

45 = root2

so by putting values we get

2 x sec^2 (45) + 3x cosec^2 (45)

= 2 × 2 + 3 x 2 = 6

so, 2sec^2 theta +3 cosec^2 theta =6
