Question

Find the arithmetic mean of the values of sin0,sin30,cos60,tan45,cot45

Answer 1

Step-by-step explanation:

sin 0°=0, sin 30°=1/2, sin 45°=1/√2, sin 60°=√3/2, sin 90° = 1

→Mean of given data = sin 0°+sin 30°+sin 45°+sin 60°+sin 90° all divided by 5

= 0 + 1/2 + 1/√2 + √3/2 + 1 / 5

= 1+√2+√3+2 / 2 × 5

= √2+√3+3 / 10
