Question

use a calculator to find the approximate value of the expression sin 1 sin 1 = (round to two decimal places as needed )

Explanation:

Step1: Set calculator to radian mode

Since the input is \(1\) (assumed to be in radians in mathematical contexts unless specified otherwise).

Step2: Calculate \(\sin1\)

Using a calculator, \(\sin(1)\approx0.8414709848\)

Step3: Round to two decimal places

Rounding \(0.8414709848\) to two decimal places. Look at the third decimal digit \(1\). Since \(1<5\), we keep the second decimal digit as it is. So \(0.8414709848\approx0.84\)

Answer:

\(0.84\)
