When x approaches zero, what is Lim [(1-cos3x) / (9xsin5x)] equal to?
Because the numerator denominator tends to zero when x tends to zero, we consider the lobita rule
The result is 3 / 20
Let f (x) be differentiable at point x = a, then what is f (a + H) - f (A-H) / h equal to when Lim h approaches 0
lim(1-5/x)∧(2x+3)
