Problem 61
Question
Use a calculator to find the value of the trigonometric function to four decimal places. $$\sin 0.8$$
Step-by-Step Solution
Verified Answer
The sin(0.8) is approximately 0.7174 when rounded to four decimal places.
1Step 1: Set the Calculator Mode
Make sure the calculator is set to radians mode. For most calculators, this can be done by accessing the settings or mode options, then selecting 'RAD'.
2Step 2: Input the Given Value
Input the given value, 0.8, into the calculator. Be careful not to confuse the decimal point with the comma used in some countries to denote thousands.
3Step 3: Use the Sine Function
Use the calculator's sine function, often denoted as 'SIN', on the inputted value. This should yield the sine value of 0.8 radians.
4Step 4: Record the Result
Take note of the result displayed on the calculator screen, rounding it to four decimal places.
