If ,- 2

Question

If ,- 2< < 2 is the solution of 4 cos ⁡ +5 sin ⁡ =1, then the value of tan ⁡ is

Accepted Answer

Correct answer: C. (c) 4+5 tan ⁡ = sec ⁡ Squaring : 24 tan^2 ⁡ +40 tan ⁡ +15=0 tan ⁡ = -10 1012 and tan ⁡ =- ( 10+ 1012 ) is Rejected. (c) is correct.

$If α, - \frac{π}{2} < α < \frac{π}{2} is the solution of 4 cos θ + 5 sin θ = 1, then the value of tan α is$
