Question

All the TRIGNOMETRIC IDENTITES.......

Answer 1

Step-by-step explanation:

heya it's Yuvraj

Sin ^2 + cos ^2 =1

1+ cot ^2 = cosec^2

1 + tan ^2 = sec ^2

Answer 2

All the TRIGNOMETRIC IDENTITES are ----

• sin0° = 0
• sin30° = 1/√2
• sin45° = 1/2
• sin60°= √3/2
• sin90° = 1

• cos 0° = 1
• cos 30° = √3/2
• cos45° = 1/2
• cos 60° = 1/√2
• cos 90° = 0

• cosec 0° = 0
• cosec 30° = √2
• cosec 45° = 2
• cosec 60° = 2/√3
• cosec 90° = 1

• sec 0° = 1
• sec 30° = 2/√3
• sec 45° = 2
• sec 60° = √2
• sec 90° = 0

• tan 0° = 0
• tan 30° = 1/√3
• tan 45° = 1
• tan 60° = √3
• tan 90° = 0

• cot 0° = 0
• cot 30° = √3
• cot 45° = 1
• cot 60° = 1/√3
• cot 90° = 0

and the formulas are ,

• sin^2theta + cos^2theta =1
• 1 + cosec^2 theta = cot^2theta
• 1 + sec^2theta = tan^2theta
• sintheta / costheta = tan theta
