Q2 Free Limit at Infinity calculator - solve limits at infinity step-by-step I am having trouble figuring out how to answer this question by determining the degree of the numerator and/or denominator: $$\lim_{x\to\infty}\frac{\sqrt{x^3 +7x}}{\sqrt{4x^3+5}}$$ I have tried de I am stuck with this limit problem $$\lim_{x \to 0} \frac{x}{\sin(2x)\cos(3x)} $$ Any hints are appreciated. 1) lim x ? 0 ( (square root of 1+9x)- (square root of 1-7x)) / x 2) lim x?0 (x-sinx) / x-tanx 3 Calculate the limit \lim \limits_{x \to 2} \left(\frac{x^2+2x-8}{x^2-2x}\right), although x\neq 2 Find all values of real number a such that \lim_{x\to1}\frac{ax^2+a^2x-2}{x^3-3x+2} exists. Suatu fungsi memetakan keluaran f(x) untuk setiap masukan x. Differentiation. Divide the numerator and denominator by the highest power of x x in the denominator, which is x3 x 3. Step 1: Apply the limit value and put 0 in the place of x. For example in case of y = f (x) = 1 x, as x → ± ∞, f (x) → 0.
