Question
Which of the following is the world's second most
deepest and longest lake?Solution
• Tanganyika Lake is the second largest freshwater lake in the world by volume and the second deepest lake of any kind, with a length of 673 km and a depth of 1470 meters. • Baikal Lake is the deepest freshwater lake in the world, but it is not the second largest by length. • Superior Lake is the largest freshwater lake by area but has a much shallower depth than Tanganyika. • Great Bear Lake is smaller in both length and depth compared to Tanganyika.
If cos θ + sec θ = √5, then the value of cos³ θ+ sec³ θ is:
If 17sin A = 8, where 0
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
If (3cos A - sin A) = 2 cos (90° - A), then find the value of cot A.
What is the simplified value of the given expression?
2(sin² 15° + sin² 75°) + 4sin 30° - (2sec 60° + cot 45°)
If sec2 θ = 4, then find the value of sin2 θ + cosec (90 - θ) where 0o < θ < 90o.
...- Find the simplified value of the expression:sin 2 45 o  + sin 2 60 o  - (1/3) X tan 2 60 o
If sin(x-y) = 1  and cos(x+y) = 1 /√2  then what is measure of angle x.
