Question
The breakdown of nitrites and nitrates by bacterial
activity is known as:Solution
DenitrificationĀ is a microbially facilitated process where nitrate (NO3ā) is reduced and ultimately produces molecularĀ nitrogenĀ (N2) through a series of intermediate gaseous nitrogen oxide products
- If cos2B = sin(1.5B - 36 o ) , then find the measure of 'B'.
If sin(x + y) = 1 and sin(x - y) = (1/2), then what is the value of sinx cosx + 2sin2y + cos2y?Ā
cos (sec-1 x) is equal to ā
