Exact trig values hand trick | trigonometry | maths | fuseschoolthere are some key angles that have exact values in trigonometry. the ones we need to know.
Exact Trig Values Hand Trick Trigonometry Maths Fuseschool We’re here to help you remember all kinds of trigonometric equations with easy to follow methods. we’ll walk you through multiple memorization tactics, from mnemonic devices to the trigonometric table: a helpful chart that lists key trig values like sine, cosine, and tangent. 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°. Here i will show you a neat little trick to help you remember these common values off by heart. construct this table – with sin and cos as the row headings and the angles as the column headings. the values are going to go on the inside of the table. on the inside of the table, put the numbers 0, 1, 2, 3 and 4 like so…. 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. each finger on your right hand corresponds to an angle $ \alpha $: thumb: 0° index finger.

There are some key angles that have exact values in trigonometry. the ones we need to know are 0, 30, 45, 60 and 90. in this video we will discover one method of remember what these values are by counting fingers on our hand! in the first part we discovered a different method (constructing a table) which you may prefer. The hand trick for finding exact trig values involves using your hand to represent angles, with your palm facing towards you. each finger is labeled with an angle from 0 degrees to 90 degrees. to find the sine and cosine values, you square root the number of fingers below or above the bent finger, and divide by two. The hand trick helps in finding exact trig values by providing a visual representation of the unit circle and associating each finger with a specific trigonometric value. by using this mnemonic, you can quickly recall the values of sine, cosine, and tangent for commonly used angles without the need for a calculator or reference table. 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.
