Question
Nagpur Plan classifies roads in India into how many
categories?Solution
According to Nagpur Road Plan, Roads in India are divided into the five categories:-
A man is standing at a point 40 meters away from a tower. The angle of elevation of the top of the tower from the point is 45°. After walking 20 meters...
If 2ycosθ = x sinθ and 2xsecθ – ycosecθ = 3, then x 2 + 4y 2 = ?
If tan A = 4/3, 0 ≤ A ≤ 90°, then find the value of sec A.

If x tan 60° + cos 45° = sec 45° then the value of x2 + 1 is
If A, B and C are angles of triangle, then sin2A + sin2B + sin2C– 2cosA cosB cosC
Find the value of tan(75°) using the identity for tan(A+B).
If 2 sec 3x = 4, then the value of x:
If x = r sin A cos B, y = r sin A sin B and z = r cos A, then find x² + y² + z².
