2 see answers advertisement kennedywhite33 answer: Negative startfraction startroot 2 minus startroot 3 endroot endroot over 2. The exact value cannot be represented as a single number because it is a non terminating. Web what is the exact value of cos 105°? The value of sin 195 degrees can be calculated by constructing an angle of. Web what is the exact value of tan 195°? What is the exact value of cos 15°? The key is to write 195 degrees as the sum or difference of two numbers whose sine and cosine are known. (so would (60 +135)∘) cos195∘ = cos(45∘. In this case, 195° 195 ° can be split into 135+60 135 +.
Web find two special angles that add up to 195∘. Web finding exact values for the tangent of the sum or difference of two angles is a little more complicated, but again, it is a matter of recognizing the pattern. Web what is the exact value of tan 195°? What is the exact value of cos 15°? Web cos (195°) cos ( 195 °) first, split the angle into two angles where the values of the six trigonometric functions are known. All you need to do is provide the inputs and click the calculate. Web find two special angles that add up to 195∘. This problem has been solved!. How can we find the exact values using the calculator? Finding the sum of two. The key is to write 195 degrees as the sum or difference of two numbers whose sine and cosine are known.
