How To Remember The Values Of Sin 60 Sin 30 Sin 45 Etc In my opinion, the best way to remember exact values for sine, cosine and tan of 30, 45 and 60 degrees. ️ ️ ️ support the channel ️ ️ ️ www. Divide your sine values by the cosine values to fill the tangent row. simply speaking, tangent = sine cosine. therefore, for every angle, take its sine value and divide it by its cosine value to calculate the corresponding tangent value. [5] to take 30° as an example: tan 30° = sin 30° cos 30° = (√1 2) (√3 2) = 1 √3.

How To Remember The Trigonometric Table 9 Steps With Pictures In this video i explain an easy way to memorize the sine and cosine of the main angles that come up in geometry and trigonometry; 30, 45, and 60 degrees. 🙂 30, 45, and 60 degrees. :). How to use the trig ratios of special angles to find exact values of expressions involving sine, cosine and tangent values of 0, 30, 45, 60 and 90 degrees? example: determine the exact values of each of the following: a) sin30°tan45° tan30°sin60°. b) cos30°sin45° sin30°tan30°. show video lesson. I explain how to memorise the values of sin, cos and tan for 0, 30, 45, 60 and 90 degrees by a simple trick using your hand. 1. evaluate the following. the angle is not commonly found as an angle to memorize the sine and cosine of on the unit circle. 2. write the expression in terms of common angles. we know the cosine and sine of common angles like and it will therefore be easier to deal with such angles.
