We can exploit a scientific calculator to attain the trigonometric worth of one angle.

Example:Find the worth of cos 6.35˚.



cos 6.35˚ = 0.9939 (correct come 4 decimal places)

Example:Find the value of sin 40˚ 32’.



sin 40˚32’ = 0.6499 (correct to 4 decimal places)

Example:Find the worth of x because that the complying with triangle. (Give your answer correct to 2 decimal places)




x = 6.21 × sin 31.3˚ = 3.23 units

Determining Trigonometric role Values ~ above The Calculator

Using the TI 84 come find function values because that sine, cosine, tangent, cosecant, secant, and also cotangent.

Calculators room able to identify trigonometric role values in degrees and also radians. However, many calculators deserve to not return the worths in radical form. Most will return decimal approximations uneven the values room rational. The video will just use angle measure in degrees.

First, make sure that the calculator is in degree mode.

Examples:Determine the complying with trigonometric values:

sin 30°cos 45°tan (-264°)sec(102.5°)csc (432°)cot(-23.45°)
