Question
Which country has declared a national health emergency
due to 'Guillain-Barré syndrome'?Solution
Peru has declared a 90-day national health emergency due to a rise in cases of the neuro-related disorder Guillain-Barré syndrome. Guillain-Barré syndrome is a rare neurological disorder in which the body's immune system affects the nerves.
Find the maximum value of 22 sin A + 16 cos A.
If cos 2x = 1/2, then the value of x:
If (sin 3A sec 6A = 1) , then what will be the value of cos 6A?
- Find the value of sin²12° + sin²78° + cos²24° + cos²66°.
- If X = 15°, find the value of:
sin²(3X) + cos²(4X) - tan²(2X) - Simplify the following trigonometric expression:
15 cos 27° sec 63° − 9 cot 61° tan 29° If sin A - cos A = 3/7, then find value of sinA + cos B, where A is an acute angle.
If tan² 45°- cos² 60° x sin 45° cos 45° cot 30°, then find the value of 'x'.
If sin θ + cos θ = 1.2, find the value of sin θ. cos θ.
If tanθ – cotθ = a and cosθ + sinθ = b, then (b2 –1)(a2 + 4) = ?
