Question

Expert Solution

Step 1

given:

$\lim_{y \to 0} \frac{\sin (126 y)}{\sin (42 y)}$

the first step in the solution that is $\lim_{y \to 0} \frac{\sin (126 y)}{\sin (42 y)}$ is incorrect because we cannot cancel the trigonometric functions like this since the angles of the trigonometric functions are different.

as the first step is wrong we cannot write the second and third step like this.
