How do i get (cot) (csc) (sec) on my calculator?
cotx = 1/tanx, cscx = 1/sinx, and secx = 1/cosx, all by definition
e.g. to find cos 60°
= 1/cos60°
= 1/(1/2)
= 2
try it
thank you Reiny
To calculate the values of cotangent (cot), cosecant (csc), and secant (sec) on your calculator, you'll need to follow these steps:
1. Turn on your calculator and identify the trigonometric function buttons. These may be labeled as "cot," "csc," and "sec," or they may be represented by the abbreviations "cot," "cosec," and "sec." They are usually located near the other trigonometric functions like sine (sin), cosine (cos), and tangent (tan).
2. If your calculator has separate buttons for each function (cot, csc, sec), simply press the corresponding button after entering the angle measure. For example, if you want to find the cotangent of an angle, enter the angle measure (in degrees or radians) and then press the "cot" button. The calculator will display the result.
3. However, some calculators might not have dedicated buttons for cot, csc, and sec. In this case, you can use the reciprocal property of trigonometric functions.
- To find cot, enter the angle measure, calculate the tangent (tan), and then take the reciprocal (1/x). For example, if you want the cotangent of an angle, enter the angle measure, press the "tan" button, and then press the "1/x" button.
- To find csc, enter the angle measure, calculate the sine (sin), and then take the reciprocal (1/x). For example, if you want the cosecant of an angle, enter the angle measure, press the "sin" button, and then press the "1/x" button.
- To find sec, enter the angle measure, calculate the cosine (cos), and then take the reciprocal (1/x). For example, if you want the secant of an angle, enter the angle measure, press the "cos" button, and then press the "1/x" button.
Remember, calculator functions may vary slightly, but these steps should guide you in finding the cot, csc, and sec values on most scientific calculators.
