Evaluate the following, rounding to the nearest hundredth. sin 62° = ? cos 62° = ? tan 62° = ?
Understand the Problem
The question asks to evaluate the sine, cosine, and tangent of 62 degrees, and to round the answers to the nearest hundredth.
Answer
sin 62° = 0.88 cos 62° = 0.47 tan 62° = 1.88
Answer for screen readers
sin 62° = 0.88 cos 62° = 0.47 tan 62° = 1.88
Steps to Solve
- Evaluate sin 62°
Using a calculator, find the sine of 62 degrees. $$ \sin(62^\circ) \approx 0.8829 $$ Round to the nearest hundredth: 0.88
- Evaluate cos 62°
Using a calculator, find the cosine of 62 degrees. $$ \cos(62^\circ) \approx 0.4695 $$ Round to the nearest hundredth: 0.47
- Evaluate tan 62°
Using a calculator, find the tangent of 62 degrees. $$ \tan(62^\circ) \approx 1.8807 $$ Round to the nearest hundredth: 1.88
sin 62° = 0.88 cos 62° = 0.47 tan 62° = 1.88
More Information
The trigonometric functions sine, cosine, and tangent relate the angles of a right triangle to the ratios of its sides. These functions can be easily evaluated using a calculator.
Tips
A common mistake is not rounding to the correct decimal place, or not using the calculator correctly (e.g. making sure it is in degree mode).
