The Day is an annual celebration that informs the public on the dangers of using tobacco, the business practices of tobacco companies, what the World Health Organization (WHO) is doing to fight tobacco use, and what people around the world can do to claim their right to health and healthy living.
If A and B are complementary angles, then the value of-
sin A cos B + cos A sin B – tan A tan B + sec 2
Simplify (cos20°+sin 20°) /(cos20°-sin20°)
Simplify: sin (A + B) sin (A - B)
What is the value of cosec30° sec30°?
The minimum value of 77 sin θ + 36cosθ is
If tan A = 4/3, 0 ≤ A ≤ 90°, then find the value of sec A.
Simplifies-
(1 + tan²A) + (1+ 1 /tan²A)
[A] 1/ (sin²A-sin4 A)
[C] 1/ (cos2 A-sin4 A)
[B]...
If Sinθ + Cosθ =√2 Cos(90 -θ ), then find the value of Cotθ ?
...tan 20˚ x tan 23˚ x tan 67˚ x tan 70˚ = ?
