will be listed under World Heritage Site?Solution
The panel of United Nations has recommended that Australia's Great Barrier Reef should be listed as a World Heritage site that is in danger.Â
- Determine the value of :


[(sinx – 2sin 3 x)/(2cos 3 x – cosx)] 2  + 1, x ≠45 o , is equal to:
Simplify: sin 780° sin 480° + cos 120° sin 30°
If 9 sinx + 40 cosx = 41 then find tanx.
- If X = 15°, find the value of:
sin²(4X) + cos²(3X) - tan²(2X) If SecA + TanA = 2√2 + 9, then find the value of Sin A + Cos A.
Simplify (cos20°+sin 20°) /(cos20°-sin20°)
- If X = 10°, find the value of:
cos²(3X) + sin²(6X) - tan²(3X) 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...
