Step 1: Substitute the value of limit in the function. lim x → 5 ( c o s 3 ( x) ⋅ s i n ( x)) = c o s 3 ( 5) ⋅ s i n ( Step 2: Simplify the equation as we did in previous examples. lim x → 5 ( c o s 3 ( x) ⋅ s i
How to Find Limits Direct Substitution. The term direct substitution is exactly as it sounds; you directly substitute a given value into a Example 3. Let’s try direct substitution
