How to learn trigonometry table

How to Create a Table of Trigonometry Functions - dummies The angles used most often in trig have trig functions with convenient exact values. Other angles don’t cooperate anywhere near as nicely as these popular ones do. A quick, easy way to memorize the exact trig-function values of the most common angles is to construct a table, starting with the sine function and working with a pattern of fractions and radicals. Dummies has always stood for taking on complex concepts and making them easy to understand. Dummies helps everyone be more knowledgeable and confident in applying what they know. Whether it's to pass that big test, qualify for that big promotion or even master that cooking technique; people who rely on dummies, rely on it to learn the critical skills and relevant information necessary for success.

Trig mnemonics like TOA explains the tangent about as well as $x^2 + y^2 = r^2$ describes a circle. Sure, if you’re a math robot, an equation is enough. The rest of us, with organic brains half-dedicated to vision processing, seem to enjoy imagery. And “TOA” evokes the stunning beauty of an abstract ratio. I think you deserve better, and here’s what made trig click for me. • Visualize a dome, a wall, and a ceiling • Trig functions are percentages to the three shapes Motivation: Trig Is Anatomy Imagine Bob The Alien visits Earth to study our species. Without new words, humans are hard to describe: “There’s a sphere at the top, which gets scratched occasionally” or “Two elongated cylinders appear to provide locomotion”. After creating specific terms for anatomy, Bob might jot down typical • The armspan (fingertip to fingertip) is approximately the height • A head is 5 eye-widths wide • Adults are 8 head-heights tall How is this helpful? Well, when Bob finds a jacket, he can pick it up, stretch out the arms, and estimate the owner’s height. And head size. And eye width. One fact is linked to a variety of conclusions. Even better, human biology explains human thinking. Tables have legs, organizations have heads, crime bosses have muscle. Our biology offers ready-made analogies that appear in man-made creations. Now the plot twist: you are Bob the alien, studying creatures in math-land! Generic words like “triangle” aren’t overly useful. But labeling sine, cosine, and hypotenus...

Can you find the length of a missing side of a right triangle? You most likely can: if you are given two side lengths you can use the Pythagorean Theorem to find the third one. But, what if you are only given one side? Impossible? Cue sine, cosine, and tangent, which will help you solve for any side or any angle of a right triangle.

Quick confession? I never fully learned the trig derivatives. Sure, I memorized $\sin' = \cos$ and $\cos' = -\sin $ like everyone else, but the derivative of tangent? Cosecant? Forget it, magic spells. After years of searching, there's a middle ground between tedious derivation and rote memorization. Aha moment: all trig functions change using the same process: (sign)(scale)(swapped function). Here's the Table of Trig Derivatives we'll learn to fill out: As background, learn to Part 1: Learn the table First, let's learn to make the table, one column at a time: Your browser does not support the video tag. • Function: The function to derive (sin, cos, tan, cot, sec, csc) • Sign: The "primary" functions are positive, and the "co" (complementary) functions are negative • Scale: The hypotenuse (red) used by each function • Swap: The other function in each Pythagorean triangle (sin ⇄ cos, tan ⇄ sec, cot ⇄ csc) • Derivative: Multiply to find the derivative Tada! This procedure somehow finds derivatives for trig fucntions. Learning tips: • Think "triple S": sign, scale, swap • You've likely memorized $\sin' = \cos$ and $\cos' = -\sin$. Fill in those rows to kickstart the process. Normally, I prefer insight to memorization. But practically, you're asking about trig derivatives because you have a test, and I want to help you now. Like a multiplication table, after filling in the entries, we notice patterns. Could $\sin' = \cos$ and $\csc' = -\csc \cot$ have something in common? You ...
