When will PM Narendra Modi launch the Gyan Bharatam

What is the value of [(sin x + sin y) (sin x – sin y)]/[(cosx + cosy) (cosy – cosx)]?

If cos² x + sin x = 5/4, then find the value of 'sin x'.

cot 4˚ x cot 47˚ x cot 42.3˚ x cot 43˚ x cot 47.7˚ x cot 86˚= ?

The Value of (sin38˚)/(cos52˚) + (cos12˚)/(sin78˚) - 4cos²60˚ is

If 2sin y + cos y = √3 sin y, then find the value of tan y

What is the value of [(tan 5θ + tan 3θ)/4 cos 4θ (tan 5θ – tan 3θ)]?

Evaluate the following:

sin 50° × cos 20° − sin 20° × cos 50°

The minimum value of 12 sin θ + 5 cosθ is
