Question

using a calculator, evaluate the expression. round to four decimal places. (be sure the calculator is in radian mode.) sin (arctan (2)) a. -0.8172 b. 0.8944 c. 0.0000 d. undefined

Explanation:

Step1: Calculate arctan(2)

Using a calculator in radian mode, $\arctan(2)\approx1.107148718$

Step2: Calculate sin of the result

$\sin(1.107148718)\approx0.8944$
