and cot 30
by
the ratio concepts​

Answer 1

Answer:

at first, please mark me brainliest answer please

Step-by-step explanation:

sin 30° = cos 60° = 1/2

tan 30° = cot 60° = 1/√3

sin 60° = cos 30° = √3/2

tan 60° = cot 30° = √3

sin 45° = cos 45 ° = 1/√2

tan 45° = cos 45° = 1

sin 0° = cos 90° = 0

sin 90° = cos 0° = 1

cosec 30° = sec 60° = 2

cosec 45° = sec 45° = √2

cosec 60° = sec 30° = 2/√3

cosec 90° = sec 0° = 1

cosec 0° = sec 90° = 1/0 .. .... ( infinity )

tan 90° = cot 0° = 1/0 ......... ( infinity )
