Number of Hindi books = 140/0.35 = 400 Number of English books = 400 × (3/2) = 600 Required difference = 600 – 400 = 200
Simplify: sin (A + B) sin (A - B)
If A + B = 450 , then the value of 2(1 + tanA) (1 + tanB) is:
If sec²x + csc²x = 10, find the value of tan²x + cot²x.
What is the value of cosec30° sec30°?
Find the value of [cos25°−sin65°]/ [cos25°+sin65°].
If cosα/sinβ =10 and cosα/cosβ =11 then find the value of cos²β=?
If SecA + TanA = 2√2 + 9, then find the value of Sin A + Cos A.
