Using differentials or linearization, estimate \tan 2^{\circ}

Question:

Using differentials or linearization, estimate {eq}\tan 2^{\circ} {/eq}

Linear Approximation

Finding the value of trigonometric functions can be difficult when they're not the angles defined in the unit circle. We can instead use a linearization to construct a linear approximation that will estimate these hard to calculate values.

{eq}L(x) = f(a) + f'(a) (x-a) {/eq}

In order to construct the linearization of this function, we need to chose where to center our approximation. Since we're asked for the value of...
