Evaluate the Limit

Problem

(lim_x→0)((3*(1−cos(x)))/x)

Solution

1. Factor out the constant 3 from the limit using the constant multiple rule for limits.

(lim_x→0)((3*(1−cos(x)))/x)=3⋅(lim_x→0)((1−cos(x))/x)

2. Identify the standard trigonometric limit identity which states that the limit of (1−cos(x))/x as x approaches 0 is 0

(lim_x→0)((1−cos(x))/x)=0

3. Substitute the value of the standard limit back into the expression.

3⋅0=0

Final Answer

(lim_x→0)((3*(1−cos(x)))/x)=0
