Question

Simplest way to learn the trigonometry table.

Answer 1

first learn the value of sin standard angles then reverse it to get value of cos standard angles( sin90=cos0, sin60=cos30, sin45=cos45...) then divide the sin standard angles with the respective cos standard angles the result will be tan standard angles then again revers tan standard angles to get value of cot standard angle(tan90=cot0, tan60=cot30, tan45=cot45...) then divide tan by the cot to get the sec standard angles then reverse it to get cosec standard angles(sec90=cosec0, sec60=cosec30, sec45=cosec45...)
I think this is the easiest way to learn

Answer 2

Sin30° = cos60° = 1/2
Sin45° = cos45° = 1/√2
Sin60° = cos30° = 2/√3
Sin90° = Cos0° = 1

tan30 = cot60 = 1√3
tan45 = cot45 = √3
tan60 = cot30 = 2√3

Cosec30 = sec60 = 2
Cosec45 = sec 45 = √2
Cosec60 = Sec3O = 2/√3
