Trigonometry Tricks Youtube Exact trig values hand trick | trigonometry | maths | fuseschoolthere are some key angles that have exact values in trigonometry. the ones we need to know. Pretend you’re in the middle of your dome, about to hang up a movie screen. you point to some angle “x”, and that’s where the screen will hang. the angle you point at determines: sine (x) = sin (x) = height of the screen, hanging like a sign. cosine (x) = cos (x) = distance to the screen along the ground [“cos” ~ how “close. Well use this easy trick to help you out! hold your left hand with your palm to you. 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. put your left hand palm towards you, thumb up, fingers. In these lessons, we will learn some mnemonics or tricks to remember the trigonometric ratios of special angles: 0°, 30°, 45°, 60° and 90° and also in radians. 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.

The unit circle hand trick is an unbelievably simple and effective way to remember trigonometric values without consulting a chart. it works by assigning a letter in the alphabet to a certain angle. this allows you to quickly recall the value of the angle simply by looking at your fingers. while this technique is extremely helpful for those. Verifying trigonometric identities is quite a difficult concept in pre calculus. here are my general tips and tricks when trying to verify trigonometric identities. have the fundamental trig identities (which can be found here) memorized and in the back of your mind at all times. converting all trig functions to sine and cosine is often an.
