How To Find The Trigonometric Ratios Of Special Angles Using Fingers
Trigonometric Ratios Of Special Angles Worksheet With Answers Pdf In this video, i explain an easy and smart method of finding the trigonometric ratios of special angles using your fingers . This method uses the fingers of one hand to easily remember the sine, cosine, and tangent values for the angles 0°, 30°, 45°, 60°, and 90°. the trick is to count the number of fingers to the left and right of the finger representing a specific angle.
Trig Ratios Of Special Angles Worksheet With Answers Pdf All we need today is just going to be at your fingertips! this “math hack” allows you to find the exact trigonometric values of very common sine and cosine functions. let’s begin! through this method, you can find the sine and cosine functions of 5 specific angles: 0°,30°,45°,60° and 90°. Hold up your right hand with all five fingers extended. each finger will represent a specific angle, starting from the pinky (representing 0°) and moving towards the thumb (representing 90°) similar to the following figure. Trigonometry is one of the most widely used sections of mathematics. learn about trigonometric ratios. learn a cool trick of trigonometry on fingers. Step 3: find a trig problem. step 4: hold down the finger assigned for that angle. for example: hold down your ring finger for π 6. step 5: know the following formulas. “bottom fingers” refer to how many fingers are “below” the finger you’ve held down. “top fingers” refer to how many fingers “above” the finger you’ve held [link] thumb counts.

The hand trick method demonstrated in this video provides a fun and memorable way to recall exact trigonometric values for special angles. this technique is a great tool for students learning trigonometry and can be used as a valuable resource during study sessions. There are several ways to memorize the main values of trigonometric functions. if you spread your fingers of your right hand, then the little finger and thumb form the first quadrant of the cartesian coordinate system. Think about each of your fingers having a value in degrees; pinky = 0, ring finger = 30, middle finger = 45, pointy finger = 60, and thumb = 90. first we will go over how to retrieve the cosine of an angle. The following videos show some math tricks to help you remember the values of a unit circle and trig ratio of special angles in degrees (0, 30, 45, 60, 90) and also in radians.
