Answer 2

Trigonometry is a subject which deals with triangles specially right angled Triangle. So, Let us see the trigonometric ratios.

Sine and Cosines:
sin 0° = cos 90°. = 0
sin 30° = cos 60° = 1/2
sin 45° = cos 45° = 1/√2
sin 60° = cos 30° = √3/2
sin 90° = cos 0°. = 1

Tangents and Cotangents:
tan 0° = cot 90° =0
tan 30° = cot60°= 1/√3
tan 45° = cot 45° = 1
tan 60° = cot 30° = √3
tan 90° = cot 0°= undefined


Cosecants and Secants:
cosec 0° = sec 90° = undefined
cosec 30°= sec 60° = 2
cosec 45°= sec 45° = √2
cosec 60°= sec 30° = √2/3
cosec 90°= sec 0° = 1
