Let us write 120° as a sum of 90° and 30°. ∴ cos1200 = −cos600 = − 1 2. Web with the help of the trigonometry formula, sino (90 + a) = coso a ,we can determine sin 120 exact value. Web apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Step 2 apply the sumof anglesidentity. Sin(60) sin ( 60) the. Web trigonometry find the exact value cos (120+45) cos (120 + 45) cos ( 120 + 45) add 120 120 and 45 45. All you need to do is provide the inputs and click the calculate. This can be deduced from the standard angles for cosine. Cos120 = cos(180 − 60) = −cos60 = − 1 2.

Cos(165) cos ( 165) the exact value of cos(165) cos ( 165) is − √6+ √2 4. Let us write 120° as a sum of 90° and 30°. Web with the help of the trigonometry formula, sino (90 + a) = coso a ,we can determine sin 120 exact value. Cos(165) cos ( 165) the exact value of cos(165) cos ( 165) is − √6+ √2 4. Cos120 = cos(180 − 60) = −cos60 = − 1 2. Cos450 = 1 √2 = √2 2. Sin(60) sin ( 60) the. To locate the terminal point of the given angle on the unit circle,. ∴ cos1200 = −cos600 = − 1 2. Step 2 apply the sumof anglesidentity. As we know, sino (90° + 30°) = sino 120 degrees.
