# G(x) = integral from 1 to x of tan t dt. A) Find G(1). B) Find G prime (pi/6).

## Question:

{eq}G(x) = \int_{1}^{x} \tan t \, \mathrm{d}t {/eq}

A) Find {eq}G(1) {/eq}.

B) Find {eq}{G}'(\frac{\pi}{6}) {/eq}.

## Fundamental Theorem of Calculus:

According to the fundamental theorem of calculus, if f(x) is a continuous real-valued function defined on a

closed interval (a, b) and F(x) is defined by the integral

{eq}F(x) = \int_{a}^{x} f(t) dt {/eq}

then F(x) is uniformly continuous and differentiable in (a,b) and

{eq}F'(x) = f(x) {/eq}

We know that the function G(x) is defined by the integral

{eq}G(x) = \int_{1}^{x} \tan t \, \mathrm{d}t {/eq}
