For the following functions, can you define ... ... sin(3x)/x: lim x→0 sin(3x). 5x3 − 4x. = lim x→0 sin(3x) x(5x2 − 4). = lim x→0 sin(3x) x. ·. 1. 5x2 − 4. = lim x→0. [They replaced u by x instead of by 3x + 2]. According to Maple, the answer is: 1/12 (cos (3x + 2)). 3 sin (3x +2)+1/8 cos (3x + 2) sin (3x +2)+3/8x + 1/4. But ... Dec 16, 2024 ... Ex 7.6, 2 sin 3 sin 3 sin 3 = sin 3 sin 3 = cos 3 3 1 cos 3 3 = cos 3 3 + cos 3 3 = cos 3 3 + sin 3 3 . 3 + = Sep 11, 2014 ... The limit $$\lim_{x \rightarrow 0} \frac{\sin(x)}{x} = 1$$ is an important and standard one, but proving it takes a bit of ingenuity. The period of the sin(3x) sin ( 3 x ) function is 2π3 2 π 3 so values will repeat every 2π3 2 π 3 radians in both directions. y = sin x + cos x ⇒. 9. y = 4x + √1 − x ⇒. 10. y = (x + 1)/p5x2 + 35 ⇒. 11. y = x5 − x ⇒. 12. y = 6x + sin 3x ⇒. 13. y = x + 1/x ⇒. 14. y = x2 + 1/x ... ... the Concept and Vocabulary Check.
