Problem 64
Question
Use a calculator to find the value of the trigonometric function to four decimal places. $$\tan 3.7$$
Step-by-Step Solution
Verified Answer
The answer will vary depending on the model of calculator used, however it should be around -0.6435 when rounded to four decimal places.
1Step 1: Setting the Calculator
Ensure your calculator is in the correct mode to handle decimal degrees. Some calculators may require you to switch between degree and radian modes.
2Step 2: Input the Function
Input \(\tan(3.7)\) into the calculator. Make sure to include the parentheses to indicate that the tangent function is acting on the number 3.7.
3Step 3: Compute
Press the equals button or whatever button your particular calculator uses to compute the answer.
4Step 4: Read the Result
Finally, read the result from the calculator and round it to the required number of decimal places. Note that rounding should only be done at the very end of the calculation, to avoid rounding errors.
