To find sin(theta) when given that cos(theta) = 5, you can use the Pythagorean identity for trigonometric functions. First, recognize that cos(theta) = adjacent/hypotenuse, and since it's given as 5, you can represent the adjacent side as 5 and the hypotenuse as 1. Then, using the Pythagorean theorem, you can find the length of the opposite side (sin(theta)). So, sin(theta) = sqrt(1^2 - 5^2) = sqrt(1 - 25) = sqrt(-24). Since the square root of a negative number isn't a real number, there's no real solution for sin(theta) when cos(theta) = 5.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
